San Francisco 4th and King Street, 4th and King (previously 4th & Townsend), or Caltrain Depot is the north end of the Caltrain commuter rail line to the San Francisco Peninsula and Santa Clara Valley, and is a major area transit hub. It is next to a Muni Metro light rail station, which provides connections to downtown San Francisco and Bay Area Rapid Transit.

The station is in the Mission Bay/China Basin area, bordered on the north by Townsend Street, east by 3rd Street, west by 4th Street and south by King Street. It opened on June 21, 1975, replacing a station built in 1914 at 3rd and Townsend, one block away.

The Muni extension to the station was opened in 1998.

The Downtown Rail Extension project to the rebuilt Transbay Terminal includes the construction of an underground 4th and King station. The underground station will be next to the current station on the Townsend side. Several platforms on the current station will be retained as the terminal for non-electric trains, such as trains to Union City across Dumbarton Rail Bridge, trains to Gilroy, and trains that won't fit into the new station, as the new station will only have six tracks for Caltrain to use. Until that time, California High-Speed Rail trains may also utilize the existing station.

All 96 weekday trains and all Saturday and Sunday trains utilize the station as a terminal; the station is unstaffed.
