Busan Metro Line 4 ({{lang|ko|4호선}}) is a rubber-tyred metro line of the Busan Metro network that connects part of Gijang-gun, Busan, and upper Haeundae-gu, Busan, into Dongnae-gu, Busan Korea. It is operated by the Busan Transportation Corporation. Opened on 30 March 2011,{{cite news| url=http://news.naver.com/main/read.nhn?mode=LSD&mid=sec&sid1=102&oid=001&aid=0004986721| title='국내 첫 무인경전철' 부산도시철도 4호선 개통| website=Naver| date=30 March 2011| language=ko}} the line is a rapid transit (metro) system consisting of 14 stations - 8 underground, 1 on-ground, and 5 above-ground.{{cite web|url=http://www.subway.busan.kr/korea/06/09_01_01.php |title=사업개요 |website=부산교통공사 |accessdate=14 March 2010 |url-status=dead |archiveurl=https://web.archive.org/web/20100111192354/http://www.subway.busan.kr/korea/06/09_01_01.php |archivedate=11 January 2010 }} The line color is blue. A trip through the entire line takes about 24 minutes. Unlike lines 1 to 3 of Busan Metro, the trains are driverless and run with pneumatic tires on concrete track (Roll way) between two guide bars. Line 4 was originally planned to be simply a branch of Line 3 (similar to Seoul Subway Line 2's Sinjeong and Seongsu branches), but was turned into its own line later.

Line 4's station signs have blue frames, sharing their design with the station sign design used in some stations of Line 1, such as Seomyeon and Dongnae. Their main body is white and circled by a blue frame and the station name is printed in big Hangul near the top with smaller English and Hanja names near the bottom, with the English name having the station number beside it. The arm that points to the next station has that station's name in it and a pointed end, while the arm that has the previous station's name printed on it and points to that station has a concave indent.

Lines 3 and 4

While Busan Metro Line 3 was being planned, the planners thought about making what is now Busan Metro Line 4 the 2nd phase of Busan Metro Line 3. However, for several reasons, they have made this 2nd phase into a new line called Busan Subway Line 4.

Archaeology

Compared to Line 3, Line 4 took quite a long time for its construction. There are many reasons for this; however the most significant one is that there were many artifacts found in the construction site of the line, including those from the time of the Three Kingdoms of Korea and the Joseon dynasty. These artifacts had great historical value,{{cite web| url=http://www.kookje.co.kr/news2006/asp/center.asp?gbn=sr&code=0100&key=20050715.22001221447| archive-url=https://web.archive.org/web/20151222090244/http://www.kookje.co.kr/news2006/asp/center.asp?gbn=sr&code=0100&key=20050715.22001221447| url-status=dead| archive-date=22 December 2015| title=반송선<도시철도 3호선 2단계>, 문화재에 발목잡히나| website=엄창현, 오상준| accessdate=28 March 2010}} so they caused the completion date of the line to be delayed from its original date of opening in 2008. Some of these artifacts are being displayed inside a historical museum dedicated to this in Suan Station (the museum opened on 28 January 2011).
