Golden Gate Ferry is a commuter ferry service operated by the Golden Gate Bridge, Highway and Transportation District in San Francisco Bay, part of the Bay Area of Northern California, United States. Regular service is run to the Ferry Building in San Francisco from Larkspur, Sausalito, Tiburon, and Angel Island in Marin County, with additional service from Larkspur to Oracle Park and Chase Center. The ferry service is funded primarily by passenger fares and Golden Gate Bridge tolls. In 2023, Golden Gate Ferry had a ridership of 1,299,200, or about 3,500 per weekday as of the fourth quarter of 2023.

The Golden Gate Bridge, Highway and Transportation District is a special-purpose district that owns and operates three regional transportation assets in the San Francisco Bay Area: the iconic Golden Gate Bridge, the Golden Gate Ferry system and the Golden Gate Transit system. All three assets connect Marin County with San Francisco. In the 1950s and 60s, officials in charge of the Golden Gate Bridge District coordinated to kill the popular BART extension into Marin County in order to preserve their own toll revenues.
