Seoul Subway Line 4 of the Seoul Metropolitan Subway (dubbed the blue line) is a long line crossing from the southwest to the northeast across the Seoul National Capital Area. The southern portion of the line is divided into the Gwacheon and Ansan Lines, but this does not affect the trains which run on it, most of which run all the way from one end of the line to the other. The southern terminus (Oido) is in Jeongwang 4-dong, Siheung City, and the northern terminus (Danggogae) is in Sanggye 4-dong, Nowon-gu, northern Seoul.

The line 4 was built between 1980 and 1994. Its total length in Seoul is 31.7 km. It will shortly be extended beyond Oido to Incheon, as the Suin Line is being rebuilt from Suwon to Incheon and this will merge with Line 4 at Hanyang University. Trains on both lines will have services to and from Incheon.
