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 Caltrain Downtown 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. 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.

4th and King is one block from AT&T Park, the home of the San Francisco Giants. Caltrain usually operates special trains to transport fans to baseball games. Special trains usually depart about fifteen minutes after the last out. One special train, leaving 15 minutes after the last out, expresses to San Carlos, then stops at every station between San Carlos and San Jose Diridon. This train is not available for daytime weekday games. Giants fans can either walk or take the Muni to the ballpark. Muni operates special trains from Caltrain to the ballpark on game days.
