The Stephen F. Austin Lumberjacks and Ladyjacks are composed of 16 teams representing Stephen F. Austin State University (SFA) in intercollegiate athletics. Stephen F. Austin teams participate in Division I as a member of the Southland Conference (SLC), having rejoined that conference on July 1, 2024 after three years in the Western Athletic Conference (WAC). The football team competes in the NCAA Division I Football Championship Subdivision (FCS, formerly known as Division I-AA) for football in the SLC. The only SFA sport not sponsored by the SLC is women's bowling, which competes in Conference USA (CUSA).

On July 1, 2021, SFA was one of five institutions announced as future members of the WAC, alongside three other Southland members from Texas (Abilene Christian, Lamar, Sam Houston) plus Big Sky Conference member Southern Utah.{{cite press release|url=https://wacsports.com/general/2020-21/releases/20210113xbg9zk |title=WAC Announces Expansion, Plans to Reinstate Football |publisher=Western Athletic Conference |date=January 14, 2021 |access-date=January 15, 2021}} Initially, all five schools were to join in July 2022, but the entry of SFA and the other Texas schools was moved to 2021 after the Southland expelled its departing members.{{cite press release|url=https://wacsports.com/general/2020-21/releases/20210121f62s76 |title=WAC Announces Expedited Entrance for Four Texas Institutions |publisher=Western Athletic Conference |date=January 21, 2021 |access-date=January 25, 2021}} Because the WAC does not sponsor beach volleyball, SFA joined the Atlantic Sun Conference (then officially known as the ASUN Conference) for that sport.{{cite press release|url=https://asunsports.org/sports/beachvball/2021-22/releases/20220119vn82co |title=11th Season of #ASUNBVB Begins This Weekend |publisher=ASUN Conference |date=February 24, 2022 |access-date=August 29, 2022 |quote=Stephen F.

SFA football played the 2021 and 2022 seasons in a football-only alliance between the WAC and the ASUN. After the 2022 season, the WAC and ASUN fully merged their football leagues under the new identity of United Athletic Conference.{{cite press release|url=https://wacsports.com/sports/fball/2022-23/releases/uacfbrelease |title=ASUN-WAC Football Partnership Formally Rebrands as the United Athletic Conference |publisher=Western Athletic Conference |date=April 17, 2023 |access-date=April 21, 2023}}

On July 1, 2024, SFA officially rejoined the SLC for all sports except women's bowling, which remains in Conference USA.{{cite web | url=https://sfajacks.com/news/2024/5/29/sfa-accepts-bid-to-southland-conference-for-2024-25-season | title=SFA Accepts Bid to Southland Conference for 2024-25 Season }}
