Mountain Lake Park is a 14-acre (5.7 ha) San Francisco park in the Richmond District neighborhood, located north of the intersection of Lake and Funston. It was designed by engineer William Hammond Hall in the late 19th century, circa 1875. Hall also designed Golden Gate Park and was significantly influenced by Frederick Law Olmsted.

The Richmond District is a neighborhood in the northwest corner of San Francisco, California, developed initially in the late 19th century. It is sometimes confused with the city of Richmond, which is 20 miles (32 km) northeast of San Francisco.
