Choji Station (Korean: 초지역) is a commuter railway station on Seoul Subway Line 4, the Suin–Bundang Line and the Seohae Line in Ansan, South Korea. Trains on Line 4 utilize what is officially named the Ansan Line within the city of Ansan, as do those on the Suin-Bundang Line, which stop at the station on the same tracks using the same platforms.

The station opened as Gongdan Station. In 2012, the city government of Ansan announced that this station would be officially renamed to Choji Station at the end of June that year.
