Colma station is a Bay Area Rapid Transit (BART) station located in unincorporated northern San Mateo County, California adjacent to the incorporated town of Colma and city of Daly City. The station is served by the Red and Yellow lines. Colma station is situated in a small valley shared with BART's Daly City Yard and a large parking garage. The station has three tracks, with an island platform between the two eastern tracks and a side platform next to the western track. Only the two eastern tracks are used for revenue service.
A former station, near the same site, was served by the Southern Pacific Railroad Ocean View Branch from 1863 to 1928. It was relocated and restored as a museum in the early 2000s. The BART yard was constructed in 1984–1988, and the station was added in 1996.
