San Francisco Maritime National Historical Park, Maritime historical park in Fisherman's Wharf, San Francisco, United States

San Francisco Maritime National Historical Park is a maritime history site at Aquatic Park Cove, covering an information center, a research facility, and several old ships docked at Hyde Street Pier. The ships sit in the water and can be toured most days, while the other buildings spread along the old waterfront district.

The San Francisco Maritime Museum opened in 1951, showing Alma de Bretteville Spreckels's model ships from the 1939–40 Golden Gate International Exposition; she feuded with founding director Karl Kortum and got little credit. The National Park Service acquired the collections in 1978, and the park was authorized in 1988. Its ships, from the 1886 Balclutha to the 1914 Eppleton Hall, are moored at Hyde Street Pier.

The name comes from the city's seafaring past, when hundreds of sailing ships and steamers moved through San Francisco Bay. Visitors can step aboard the vessels and see how sailors lived, worked, and supplied the West Coast with goods.

The visitor center, Hyde Street Pier and the maritime museum stand together at the foot of Hyde Street, at the western end of Fisherman's Wharf; the cable car Beach and Hyde Street terminal adjoins the site, and the F Market streetcar stop is about five minutes east. Park headquarters and the research center are in Fort Mason, roughly ten minutes on foot to the west. The research center admits visitors by appointment only.

One of the cargo ships was originally built as a ferry and later carried cars and trains across the bay before bridges took over the traffic. Another vessel sailed as far as Alaska, bringing supplies to remote coastal towns that were hard to reach by land.
