Seodongtan Station () is a station on Line 1 of the Seoul Metropolitan Subway. It serves the cities of Hwaseong and Osan in Gyeonggi-do, South Korea. The station takes its name (literally West Dongtan) from its local area of the city of Hwaseong, but straddles the border with Osan, in which it is mostly located and its postal address lies.
History Seodongtan Station was opened on February 26, 2010, beside Byeongjeom Depot. It primarily serves residents who reside in Dongtan New Town.
Seodongtan branch will be extended to Dongtan station after the construction of Dongtan–Indeogwon Line.
