East Brother Island Lighthouse is a lighthouse located on East Brother Island in San Rafael Bay, near the tip of Point San Pablo in Richmond, California. It marks the entrance to San Pablo Bay from San Francisco Bay.

Built in 1874 and automated in 1969, the lighthouse was designed in the American Stick style by Paul J. Pelz, who also designed East Brother Island's sister stations, Point Fermin Light in San Pedro CA, Mare Island Light, in Carquinez Strait, California (demolished in the 1930s), Point Hueneme Light in California (replaced in 1940), Hereford Inlet Light in North Wildwood, New Jersey, and Point Adams Light in Washington State (burned down by the Lighthouse Service in 1912), all in essentially the same style. The former keeper's house began operating as a bed and breakfast in 1980.
