The Eureka Valley Station was an underground streetcar station in San Francisco, California, in use from 1918 until 1972. It was located inside the Twin Peaks Tunnel, very close to its eastern end, in the Eureka Valley neighborhood. Its location was chosen with the intent that it could serve as a transfer station to the Sunset Tunnel, whose east portal in early plans was to be located at the corner of Market and Eureka streets.
