Chastain started racing at the age of twelve, his interest piqued by his father's hobby racing and other kids his age racing.{{cite web |last1=Ryan |first1=Nate |title=Podcast: Ross Chastain on the 'evil business' of competing for sponsors |url=https://nascar.nbcsports.com/2018/09/21/podcast-ross-chastain-on-the-evil-business-of-competing-for-sponsors/ |website=NASCAR on NBC |date=September 21, 2018 |publisher=NBC Sports |access-date=September 26, 2018}} His home track was Punta Gorda Speedway in Punta Gorda, Florida,{{cite web|url=http://www.nbc-2.com/story/15176269/2011/07/29/local-driver-competing-in-nascar-truck-series?clienttype=printable|title=Local driver competing in NASCAR truck series|date=July 29, 2011|publisher=NBC-2 WBBH|access-date=June 3, 2012|location=Ft.

After making the move to Charlotte in mid-2011, Chastain took over the No. 66 Turn One Racing entry in the NASCAR Camping World Truck Series after Justin Marks vacated the seat. His first Truck race, at Lucas Oil Raceway at Indianapolis, was his first race with live pit stops.{{cite web |title=The Dale Jr. Download: 240 - Chastain: A Self-Made Story |url=https://player.fm/series/the-dale-jr-download-dirty-mo-media/ep-240-chastain-a-self-made-story |website=player.fm |access-date=November 14, 2018 |archive-date=April 3, 2019 |archive-url=https://web.archive.org/web/20190403201135/https://player.fm/series/the-dale-jr-download-dirty-mo-media/ep-240-chastain-a-self-made-story |url-status=dead }} He finished 10th in that event."Young driver ready for next step".

At Homestead-Miami Speedway, rain prevented the Turn One team from making the race, so the team bought an RSS Racing start and park entry and ran the full race, finishing two laps down. It was later announced that Chastain would compete for Rookie of the Year honors with SS-Green Light Racing in 2012.{{cite web|url=http://www.nascar.com/news/120125/ross-chastain-joins-ss-green-light-racing-for-2012-truck-series/index.html|title=Chastain joins SS Green Light Racing for 2012|date=February 3, 2012|publisher=NASCAR |access-date=June 3, 2012}} Driving the No. 08 truck sponsored by the National Watermelon Association and National Watermelon Promotion Board,{{cite web|url=http://www2.highlandstoday.com/business/agri-leader/2012/mar/07/1/nascar-driver-hauls-the-fruit-for-watermelon-group-ar-366114/|archive-url=https://archive.today/20130125033543/http://www2.highlandstoday.com/business/agri-leader/2012/mar/07/1/nascar-driver-hauls-the-fruit-for-watermelon-group-ar-366114/|url-status=dead|archive-date=January 25, 2013|title=NASCAR driver hauls the fruit for watermelon group|last=Carter|first=Chip|date=March 7, 2012|work=Highlands Today|publisher=The Tampa Tribune|access-date=June 3, 2012|location=Tampa, FL}} he scored a career-best finish of seventh in the second race of the season at Martinsville Speedway.{{cite web|url=http://www.miamiherald.com/2012/03/31/2724909/harvick-dominant-in-martinsville.html|title=Harvick dominant in Martinsville truck race|date=March 31, 2012|work=The Miami Herald|access-date=June 3, 2012|location=Miami, FL}} He bested his 7th-place finish with a 3rd-place finish at Bristol in August.{{cite web|url=http://www.nbc-2.com/story/19347488/ross-chastain-gets-best-career-nascar-finish-at-bristol|title=Ross Chastain gets best career NASCAR finish at Bristol|last=Barran|first=Rishi|date=August 22, 2012|publisher=WBBH-TV|access-date=August 29, 2012|location=Fort Myers, FL|archive-date=August 26, 2012|archive-url=https://web.archive.org/web/20120826103332/http://www.nbc-2.com/story/19347488/ross-chastain-gets-best-career-nascar-finish-at-bristol|url-status=dead}}

Years later, Chastain said that he initially made the move to BKR as an attempt to get in a Team Penske ride, but that BKR and Penske did not view the situation that way.

Leaving BKR after the 2013 season, Chastain moved to RBR Enterprises for a part-time schedule in the NASCAR Camping World Truck Series for 2014.{{cite web|url=http://www.mrn.com/Race-Series/NASCAR-Camping-World-Trucks/News/Articles/2014/02/Chastain-Joins-Ricky-Benton-Racing.aspx|title=Chastain Joins Ricky Benton Racing|date=February 11, 2014|publisher=Motor Racing Network|access-date=February 11, 2014|archive-url=https://web.archive.org/web/20140222172807/http://www.mrn.com/Race-Series/NASCAR-Camping-World-Trucks/News/Articles/2014/02/Chastain-Joins-Ricky-Benton-Racing.aspx|archive-date=February 22, 2014|url-status=dead}} Comments before and after the Martinsville race, as well as racing actions during the race, led the team to fire Chastain from the ride. In May, he made his debut in the Nationwide Series (now Xfinity Series) at Charlotte Motor Speedway, driving the No. 55 for Viva Motorsports.{{cite web|url=https://sports.yahoo.com/news/ross-chastain-nns-debut-charlotte-182300934--nascar.html|title=Ross Chastain to make NNS debut at Charlotte|last=Albert|first=Zack|date=May 15, 2014|publisher=Yahoo!

He then joined JD Motorsports in 2015, replacing Jeffrey Earnhardt. The opportunity emerged after Chastain raced with TriStar Motorsports at the end of the 2014 season. His car was comparable to the performances of the JDM cars, which led to a deal in the offseason. Chastain logged four top-tens on the year, ninth in the season-opening PowerShares QQQ 300, tenth at the other Daytona race, tenth at Iowa, and tenth at Darlington, and got into an altercation with Ryan Reed after a race at Richmond International Raceway. Reed claimed Chastain made too much contact on late restarts and vowed payback, while Chastain simply brushed the incident off as a difference of opinions in short-track racing.{{Cite web |last=Crandall |first=kelly |title=Ryan Reed Vows Payback on Ross Chastain |url=http://www.popularspeed.com/ryan-reed-vows-payback-on-ross-chastain/ |archive-url=https://web.archive.org/web/20150805202111/http://www.popularspeed.com/ryan-reed-vows-payback-on-ross-chastain/ |archive-date=August 5, 2015 |access-date=December 11, 2018 |website=Popular Speed}}

Chastain's 2017 Xfinity season was the best of his career, scoring a top-five at Iowa and two top tens as well as finishing 13th in points, the highest of the non-playoff drivers. He achieved this after a tight points battle with J. J. Yeley for the spot in the last four races of the season. In the second half of the season, Chastain rarely finished outside the top twenty and mainly finished in the mid-teens.

The season was marred by two fights with fellow Xfinity drivers, one with Jeremy Clements at Bristol after Clements confronted him{{Cite news|url=https://www.nascar.com/en_us/news-media/articles/2017/4/22/jeremy-clements-ross-chastain-bristol-altercation-pit-road-hauler.html|title=Chastain, Clements called to hauler after altercation|date=April 22, 2017|access-date=December 22, 2017|language=en|archive-url=https://web.archive.org/web/20170427090736/https://www.nascar.com/en_us/news-media/articles/2017/4/22/jeremy-clements-ross-chastain-bristol-altercation-pit-road-hauler.html|archive-date=April 27, 2017}} and one with Brendan Gaughan at Texas after heated on-track competition. Chastain, Gaughan, and crew members from both teams brawled behind Victory Lane after the night race. A crew member from JD Motorsports teammate Garrett Smithley was taken to the hospital with a head injury after the fight.{{Cite news|url=http://nascar.nbcsports.com/2017/11/07/ross-chastain-gives-his-side-of-brendan-gaughan-tangle-says-he-was-hit-in-back-of-head/|title=Ross Chastain gives his side of Brendan Gaughan tangle, says he was hit in back of head|date=November 7, 2017|publisher=NASCAR Talk|access-date=December 22, 2017|language=en-US}} Chastain blamed the confrontation on Gaughan, saying the Richard Childress Racing driver attacked him, but also acknowledged that he races hard and does not play favorites. Gaughan initially avoided discussing the incident with reporters{{Cite news|url=https://www.nascar.com/news-media/2017/11/05/news-media20171105brendan-gaughan-ross-chastain-tussle-after-xfinity-race/|title=Brendan Gaughan, Ross Chastain tussle after XFINITY race NASCAR.com|date=November 5, 2017|publisher=NASCAR|access-date=December 22, 2017|language=en-US}} but later boasted about the incident on SiriusXM NASCAR Radio and said that he received several text messages from fellow drivers who were happy about the incident. He did admit that he could've handled the situation later but didn't care about it.{{Cite news|url=http://nascar.nbcsports.com/2017/11/05/brendan-gaughan-on-issue-with-ross-chastain-i-finally-just-had-enough/|title=Brendan Gaughan on issue with Ross Chastain: 'I finally just had enough'|date=November 5, 2017|publisher=NASCAR Talk|access-date=December 22, 2017|language=en-US}} That opinion was likely influenced by the fact that 2017 was Gaughan's final Xfinity season, as any retaliation had to happen within the next two races.

In 2017, Chastain joined Premium Motorsports' No. 15 car for his Monster Energy NASCAR Cup Series debut in the AAA 400 Drive for Autism at Dover,{{cite web|url=https://www.teamjdmotorsports.com/team-news/breaking-news-chastain-debuts-in-cup-series-with-boost-from-delaware-office-of-highway-safety|title=Breaking News: Chastain Debuts in Cup Series with Boost from Delaware Office of Highway Safety|work=JD Motorsports|date=May 26, 2017|access-date=May 26, 2017|archive-date=September 27, 2017|archive-url=https://web.archive.org/web/20170927052457/https://www.teamjdmotorsports.com/team-news/breaking-news-chastain-debuts-in-cup-series-with-boost-from-delaware-office-of-highway-safety|url-status=dead}} an opportunity he initially resisted after being informed of the opportunity by Xfinity team owner Johnny Davis.{{Cite news|url=http://nascar.nbcsports.com/2018/04/05/how-ross-chastain-stopped-doubting-himself-and-embraced-cup-racing/|title=How Ross Chastain stopped doubting himself and embraced Cup racing|last=McFadin|first=Daniel|date=April 5, 2018|publisher=NBC Sports|access-date=April 6, 2018|language=en-US}} he finished 20th.{{cite web|url=https://www.motorsport.com/nascar-cup/news/it-was-a-dream-come-true-as-ross-chastain-finishes-20th-in-cup-debut-914436/|title="It was a dream come true" as Ross Chastain finishes 20th in Cup debut|publisher=Motorsport |last=Utter|first=Jim|date=June 4, 2017|access-date=June 5, 2017}} Chastain heard from various sources that his driving style made multiple drivers mad on-track, but Chastain says it doesn't bother him.

On the strength of a summer performance that saw him hold down the final Xfinity Series playoff spot, Chastain and Chip Ganassi Racing announced a three-race agreement for Chastain to pilot the organization's No. 42 entry for races at Darlington Raceway, Las Vegas Motor Speedway and Richmond Raceway.{{cite web |last1=Beaver |first1=Dan |title=Ross Chastain to run three Xfinity races with Chip Ganassi Racing |url=https://nascar.nbcsports.com/2018/08/23/ross-chastain-to-run-three-xfinity-races-with-chip-ganassi/ |website=NASCAR on NBC |date=August 23, 2018 |publisher=NBC Sports |access-date=September 14, 2018}} The races came at the expense of John Hunter Nemechek, who could not sell sponsorship for the races. DC Solar was announced as a backer for Chastain's effort. Chastain had previously met the CEO of DC Solar at Auto Club Speedway in 2018, and plans materialized from there.{{cite web |last1=Long |first1=Dustin |title=Long: Ross Chastain's win 'gives all the little guys hope' |url=https://nascar.nbcsports.com/2018/09/15/long-ross-chastains-win-gives-all-the-little-guys-hope/ |website=NASCAR on NBC |date=September 16, 2018 |publisher=NBC Sports |access-date=September 17, 2018}} For the first race of the trio, Chastain held top-ten spots in both practices, finishing second in first practice.{{cite web |last1=Long |first1=Dustin |title=Xfinity practice report at Darlington |url=https://sports.yahoo.com/xfinity-practice-report-darlington-182509712.html |website=Yahoo Sports |publisher=NBC Sports |access-date=September 14, 2018}} He later claimed the pole over Christopher Bell,{{cite web |last1=Long |first1=Dustin |title=Ross Chastain wins Xfinity pole for today's race |url=https://sports.yahoo.com/ross-chastain-wins-xfinity-pole-173719051.html |website=Yahoo Sports |publisher=NBC Sports |access-date=September 14, 2018}} and during the race won the first two stages.{{cite web |last1=Utter |first1=Jim |title=Ross Chastain: "I'll never forget the peaks and valleys of this weekend" |url=https://us.motorsport.com/nascar-xs/news/chastain-ill-never-forget-the-peaks-and-valleys-of-this-weekend/3169548/ |website=Motorsport.com |date=September 1, 2018 |access-date=August 14, 2019}} During the third stage, Chastain was battling for the race lead with Kevin Harvick with thirty-five laps to go.

After clearing Finchum, Harvick slid up into Chastain who then slid up into the wall. On the backstretch, Chastain hooked Harvick's machine into the outside wall, ending Harvick's day. Harvick later parked in Chastain's pit stall before giving a heated post-race interview calling Chastain "inexperienced" and saying that Chastain will "never get to drive many of them [events in top-tier cars] again. Chip Ganassi then responded on Twitter, defending Chastain's performance and stating that he "helped himself to many future opportunities"."{{cite web |last1=lott |first1=Thomas |title=Kevin Harvick rips driver who wrecked him in Xfinity race |url=http://www.sportingnews.com/us/nascar/news/nascar-xfinity-series-sports-clips-haircuts-vfw-200-kevin-harvick-comments-ross-chastain-video/1hcgrs1uy51xw1bxus9brumefs |website=Sporting News |access-date=September 14, 2018}} Chastain, for his part, finished 25th after repairs and called running up front "cool" and also saying "I don't care what Harvick says."{{cite web |last1=Long |first1=Dustin |title=Kevin Harvick calls Ross Chastain 'a really inexperienced guy in a really fast car' |url=https://sports.yahoo.com/kevin-harvick-calls-ross-chastain-214121916.html |website=Yahoo Sports |publisher=NBC Sports |access-date=September 14, 2018}}

Towards the latter part of the 2018 season, Chastain joined Niece Motorsports for some NASCAR Camping World Truck Series races. Although some were surprised at how well Chastain ran in those races, Chastain instead said that the organization was better than the community gave it credit for.

He then rebounded with a third place finish, while leading an at the time, career-high 83 laps at Las Vegas Motor Speedway and two runner-up finishes at Phoenix Raceway, and at Atlanta Motor Speedway, after recovering a two lap deficit upon crashing in lead position. Chastain scored his first career cup win at the Circuit of the Americas battling against Alex Bowman and A. J. Allmendinger. {{cite web |url=https://www.nascar.com/news-media/2022/03/27/ross-chastain-smashes-his-way-to-first-career-cup-series-win-in-last-lap-clash-at-cota/ |title=Ross Chastain smashes his way to first career Cup Series win in last-lap clash at COTA |first=Holly |last=Cain |website=NASCAR.com |publisher=NASCAR Digital Media, LLC |date=March 27, 2022 |access-date=March 28, 2022}} A month later, he claimed his second victory at Talladega.{{cite web |url=https://www.nascar.com/news-media/2022/04/24/results-cup-series-2022-talladega-geico-500-race-recap/ |title=Ross Chastain converts last-lap pass, wins Talladega thriller |first=Holly |last=Cain |website=NASCAR.com |publisher=NASCAR Digital Media, LLC |date=April 24, 2022 |access-date=April 25, 2022}} At the 2022 NASCAR All-Star Race, Chastain finished 22nd after going airborne from colliding with Kyle Busch, taking Chase Elliott out in the process.{{cite web |url=https://www.nascar.com/news-media/2022/05/22/cup-series-2022-all-star-texas-kyle-busch-chastain-elliott-crash/ |title=Kyle Busch, Chastain, Elliott eliminated from All-Star contention in heavy Stage 2 crash |website=NASCAR.com |publisher=NASCAR Digital Media, LLC |date=May 22, 2022 |access-date=May 23, 2022}} At the Indianapolis road course, Chastain crossed the line second to Tyler Reddick, but was penalized and scored 27th place for crossing the access road during the final restart.{{cite web |url=https://www.nascar.com/news-media/2022/07/31/ross-chastain-austin-dillon-penalized-after-taking-access-road/ |title=Ross Chastain, Austin Dillon penalized for short-cutting after taking access road |website=NASCAR.com |publisher=NASCAR Digital Media, LLC |date=July 31, 2022 |access-date=August 1, 2022}} He finished third at the Phoenix finale and a career-best second place in the points standings.{{cite web |url=https://www.nascar.com/news-media/2022/11/06/cup-series-championship-ross-chastain-cherishes-first-title-bout-despite-falling-short/ |title=Ross Chastain cherishes first title bout despite falling short: 'I'm so proud' |first=Zach |last=Sturniolo |website=NASCAR.com |publisher=NASCAR Digital Media, LLC |date=November 6, 2022 |access-date=November 8, 2022}}

==Feud with Denny Hamlin==

In June at Gateway, Chastain began a feud with Denny Hamlin. Early in the race, Chastain ran into Hamlin's back bumper, causing Hamlin to spin and sustain damage to his car. Fifteen laps later, Hamlin attempted to slow Chastain by blocking him at a slower-than-normal rate of speed. NASCAR intervened and told Hamlin that he "had made his point." Later in the same race, Chastain ran into Chase Elliott, causing him to spin. At the restart, Elliott pushed Chastain towards the wall while Hamlin made a tight pass to once again express his frustration. Chastain accepted fault for the incidents saying, "I just drove over my head so many times".{{Cite web |last=Long |first=Dustin |date=June 6, 2022 |title=Ross Chastain: 'I just drove over my head so many times' |url=https://nascar.nbcsports.com/2022/06/05/long-humbled-ross-chastain-says-he-drove-over-my-head-so-many-times-denny-hamlin-chase-ellioitt/ |access-date=July 12, 2022 |publisher=NBC Sports}}

Weeks later at Atlanta, Chastain spun Hamlin with 14 laps to go. This caused Hamlin, who was running in the top five, to fall to the back of the pack. Hamlin said that he had "reached his peak" when referring to dealing with Chastain.{{Cite web |date=July 11, 2022 |title=Denny Hamlin: 'Reached My Peak' With Ross Chastain |url=https://www.speedsport.com/nascar/nascar-cup-series/nascar-denny-hamlin-reached-my-peak-ross-chastain/ |access-date=July 12, 2022 |website=Speed Sport}}

=="The Hail Melon"==

In October, Chastain qualified for the Championship 4 by a thin margin at 2022 Xfinity 500 held at the Martinsville Speedway, where he, in tenth place on the last lap of the race, drove his car into the outside wall of the track in Turns 3 and 4 to pick up the unprecedented speed of up to {{convert|130|mph}}, overtaking Hamlin and four other drivers to finish in fifth place. Chastain set a record for the fastest lap during a NASCAR Cup Series race for the track.{{cite web |last=Spencer |first=Reid |date=October 30, 2022 |title=Christopher Bell wins his way into Championship 4; title field set |url=https://www.nascar.com/news-media/2022/10/30/christopher-bell-wins-way-into-championship-4-title-field-set |access-date=October 31, 2022 |website=NASCAR.com |publisher=NASCAR Digital Media, LLC}}

The "wall-riding" move, nicknamed "Hail Melon" as a portmanteau of the Hail Mary pass in American football and "watermelon" in allusion to Chastain's background, was widely commented upon in the media.{{cite news|last=Al-Khateeb|first=Zac|url=https://www.sportingnews.com/us/nascar/news/ross-chastain-move-nascar-rule-change-2023-season/e0vpvu1wur0dkfkjlcquvnee|title=Ross Chastain rule change, explained: Why NASCAR banned 'Hail Melon' wall move for 2023 season|newspaper=The Sporting News|date=February 19, 2023|access-date=August 2, 2023}} Chastain said that the move was inspired by playing the video game NASCAR 2005 on the GameCube as a kid with his brother Chad.{{Cite web |last=Albert |first=Zack |date=October 30, 2022 |title=Ross Chastain clinches Championship 4 berth at buzzer with video-game move |url=https://www.nascar.com/news-media/2022/10/30/nascar-cup-series-2022-playoffs-ross-chastain-martinsville/ |website=NASCAR.com|publisher=NASCAR Digital Media, LLC|access-date=November 2, 2022}} Overtaken rival Hamlin, who was ultimately eliminated from the playoffs as a direct result of Chastain's move, described it as a "great move", adding that "when you have no other choice, it certainly is easy to do that."{{Cite web |title=Chastain: Martinsville wall-ride inspired by NASCAR 2005 video game |url=https://www.autosport.com/nascar/news/chastain-martinsville-wallride-inspired-by-nascar-2005/10393362/ |website=www.autosport.com|date=October 31, 2022 }} Although NASCAR ruled the maneuver legal, some race competitors and commentators criticized the move's safety and called on NASCAR to prohibit the move from setting a precedent at future races.{{cite news |last1=Fryer |first1=Jenna |date=October 31, 2022 |title=Column: Chastain Rides The Wall Into NASCAR's Title Race |url=http://racing.ap.org/article/column-chastain-rides-wall-nascars-title-race |url-status=dead |language=en |publisher=Associated Press |archive-url=https://web.archive.org/web/20221201081703/http://racing.ap.org/article/column-chastain-rides-wall-nascars-title-race |archive-date=December 1, 2022 |access-date=August 6, 2024}}

Chastain started the 2023 season with a ninth-place finish at the 2023 Daytona 500.

Chastain started the 2024 season with a 21st place finish at the 2024 Daytona 500. Despite having four top-fives and nine top-tens during the regular season, Chastain would go winless and would miss the playoffs for the first time since 2021. During the playoffs, he held off William Byron to win at Kansas.{{ cite web |url=https://www.nascar.com/news-media/2024/09/29/nascar-cup-series-2024-kansas-playoff-race-recap/ |title=Chastain spoils playoff show at Kansas, posts first Cup Series win of the season |website=NASCAR |date=September 29, 2024 |access-date=September 29, 2024}} Following the Martinsville playoff race, the No. 1 was docked 50 owner and driver points and Chastain and the team were each fined {{USD}}100,000 for race manipulation, when Chastain and fellow Chevrolet driver Austin Dillon formed a blockade to allow William Byron to make the Championship 4. In addition, Surgen was suspended for the Phoenix finale.{{cite web |url=https://www.nascar.com/news-media/2024/11/05/nascar-issues-major-penalties-to-three-cup-series-teams-after-martinsville/ |title=NASCAR issues major penalties to three Cup Series teams after Martinsville |website=NASCAR |date=November 5, 2024 |access-date=November 6, 2024}}

Personal life

A native of Alva, Florida, Chastain was a watermelon farmer on his family's farm until he turned thirteen.{{cite web|last=McFadin|first=Daniel|url=http://nascar.nbcsports.com/2017/04/27/xfinity-spotlight-qa-with-ross-chastain-watermelon-farmer-turned-race-car-driver/|title=Xfinity Spotlight Q&A with Ross Chastain, watermelon farmer turned race car driver|publisher=NBC Sports|date=April 27, 2017|access-date=May 27, 2017}} He is a graduate of Riverdale High School in Fort Myers.{{cite web|url=http://www.fortmyers.org/local-teen-ross-chastain-speeds-toward-the-finish-line-in-his-first-nascar-season-race-this-friday-.html|title=Local Teen Ross Chastain Speeds Toward the Finish Line in His First NASCAR Season|last=Ramos-Williams|first=Connie|date=November 21, 2011|publisher=Greater Fort Myers Chamber of Commerce|access-date=June 3, 2012|location=Ft.

While Chastain's father raced as a hobby, Ross is the first generation of his family to race competitively. Ross started racing at age twelve after seeing his father's hobby race and seeing other kids his age race. Ross is the older brother of Chad Chastain.

Motorsports pundits and fans have come up with a variety of rhyming monikers for Chastain, such as Ross "The Boss" originally coined by Mike Joy directly following the finish to the 2022 GEICO 500 at Talladega Superspeedway which Chastain won.{{cite tweet|number=1503115879638216706|user=LASTCARonBROCK|title=.@mikejoy500 said Ross "The Boss" Chastain - it's canon now. 😄|date=March 13, 2022}}
