The Shinbundang Line (aka Sinbundang Line; Korean: 신분당선 (literally, New Bundang Line)) or DX Line is a 31 km long line of the Seoul Metropolitan Subway. It is the world's fifth subway to run completely driverless and the second completely driverless metro line to open in South Korea, after Busan Subway Line 4. It connects Gangnam Station and Gwanggyo Station in 37 minutes, a feat achieved by being the first line to operate South Korea's next-generation subway car travelling at over 90 km/h, with the fastest average speed of any subway in the country.

The initial route opened in October 2011 passed through 6 stations intersecting with three existing lines at Gangnam Station (Line 2), Yangjae Station (Line 3), and Jeongja Station (Bundang Line). Phase 2 opened on 30 January 2016 added 6 stations to the south, extending the line to serve Yongin's Suji-gu and Suwon's Gwanggyo New City. Construction for Phase 3's extension northwards to Sinsa Station is planned in 2016, with opening slated for 2022. Construction started in mid-2005, for revenue start in Sep 2011. However, because of the flooding of late July 2011, the opening was delayed and eventually opened on 28 October 2011.

There was a debate between Seongnam City and Suwon City regarding whether Migeum should be included in the Phase 2 extension of Shinbundang Line. Supporters argued that the distance between Jeongja Station and SB01, an originally planned station to follow Jeongja, would be unusually long at 3.76 km. They also argued that the inclusion of Migeum will alleviate traffic in the area. Meanwhile,the Suwon opposition claims that the inclusion would delay travel time to Gwanggyo, a planned area of Suwon in construction.
