The Sin Ansan Line (Hangul: 신안산선, Hanja: 新安山線, meaning "New Ansan Line") is the tentative name of a commuter rail line that will eventually link Cheongnyangni Station with western Gyeonggi province, passing through key areas of the Seoul metropolitan area, including Yeouido, Yeongdeungpo and Gwangmyeong Station.

Since this line is still in the planning stages, there are many possible routes on which this line could be laid, with the only definite section between Sinpung and Gwangmyeong Station. In particular, the section south of Gwangmyeong Station has led to heated disputes between the cities of Ansan and Siheung.

Ansan has requested for the line to be built almost perfectly south from Gwangmyeong Station so it terminates at Hanyang University at Ansan, passing through Seongpo-dong on the way. This would also open the possibilities for the trains on this line to travel to Suwon via the Suin Line. The consortium behind the construction of the Sin Ansan Line, however, seems to favor a line running southwest from Gwangmyeong Station and joining the Sosa-Wonsi Line, transferring with Line 4 and the Suin Line at Choji Station and terminating at southwestern Ansan. The city of Siheung has recently made a shocking request, in which the section in dispute does not pass through the city of Ansan at all, making the name "Sin Ansan Line" meaningless. The Siheung plan has the section go west from Gwangmyeong Station, intersect the Sosa-Wonsi Line at Siheung City Hall, and terminating at Wolgot Station.

The original plans had the line follow this route: (SW) - Yeongdeungpo - Yeongdeungpo Market - National Assembly - Gwangheungchang - Sinchon - (NE). Recent plans, however, indicate another possible route with less stations: (SW) - Yeongdeungpo - Yeouido - Sinchon - (NE). The list of stations below reflects the original plans of this section, but is very likely to change.

Initial maps of Line 10 - the forerunner of this line - also showed that the line could, instead of going through Sinchon - Dongnimmun - Hyehwa, pass through Gongdeok - Seoul Station - Dongdaemun Stadium. However, following the restoration of the Cheonggye Stream, under which Line 10 was to be laid, the former route seems much more likely.

Construction will begin in 2015 with the first section of this line (Gwangmyeong Station - Yeouido) is set to be opened in 2023.
