State Route 480 (SR 480) was a state highway in San Francisco, California, United States, consisting of the elevated double-decker Embarcadero Freeway (also known as the Embarcadero Skyway), the partly elevated Doyle Drive approach to the Golden Gate Bridge and the proposed and unbuilt section in between. The unbuilt section from Doyle Drive to Van Ness Avenue was to have been called the Golden Gate Freeway and the Embarcadero Freeway as originally planned would have extended from Van Ness along the north side of Bay Street and then along the Embarcadero to the San Francisco-Oakland Bay Bridge.

The Embarcadero Freeway, which had only been constructed from Broadway along the Embarcadero to the Bay Bridge, was demolished after the 1989 Loma Prieta earthquake, and Doyle Drive is now part of U.S. Route 101. SR 480 was Interstate 480, an auxiliary route of the Interstate Highway System, from 1955 to 1965. The entire route was deleted in 1991.
