The Shipyard Railway was an electric commuter rail/interurban line that served workers at the Richmond Shipyards in Richmond, California, United States, during World War II. It was funded by the United States Maritime Commission and was built and operated by the Key System, which already operated similar lines in the East Bay. The line ran from a pair of stations on the Emeryville/Oakland border – where transfer could be made to other Key System lines – northwest through Emeryville, Berkeley, Albany, and Richmond to the shipyards. It operated partially on city streets and partially on a dedicated right-of-way paralleling the Southern Pacific Railroad mainline.

The four Richmond Shipyards, in the city of Richmond, California, United States, were run by Permanente Metals and part of the Kaiser Shipyards. In World War II, Richmond built more ships than any other shipyard, turning out as many as three ships in a single day. The shipyards are part of the Rosie the Riveter/World War II Home Front National Historical Park, whose Rosie the Riveter memorial honors the shipyard workers. Shipyard #3 is listed on the National Register of Historic Places and is a California Historical Landmark # 1032.
