The San Francisco Transbay Terminal or The Transbay Terminal, was a transportation complex in San Francisco, California, United States, roughly in the center of the rectangle bounded north–south by Mission Street and Howard Street, and east–west by Beale Street and 2nd Street in the South of Market area of the city. It mainly served San Francisco's downtown and Financial District, as transportation from surrounding communities of the Bay Area terminated there such as: Golden Gate Transit buses from Marin County, AC Transit buses from the East Bay, and SamTrans buses from San Mateo County. Long-distance buses from beyond the Bay Area such as Greyhound and Amtrak also served the terminal. Several bus lines of the San Francisco Municipal Railway, or Muni, had their turnarounds' there.
