San Lorenzo Creek is a 10.7-mile-long (17.2 km) year-round natural stream flowing through Hayward, California and other neighboring unincorporated communities into San Francisco Bay at the Hayward Regional Shoreline.

Pedro Fages (1734–1794) was a Spanish soldier, explorer, first Lieutenant Governor of the province of the Californias under Gaspar de Portolá. Fages claimed the governorship after Portolá's departure, acting as governor in opposition to the official governor Felipe de Barri, and later served officially as fifth (1782–91) Governor of the Californias.
