Don Edwards San Francisco Bay National Wildlife Refuge (DESFBNWR) is a United States National Wildlife Refuge located in the southern part of San Francisco Bay, California. Its headquarters and visitor center are in the Baylands district of Fremont, next to Coyote Hills Regional Park, in Alameda County. The visitor center is on Marshlands Rd, off Thornton Ave.^[2]

Most of the refuge stretches along the marshy shoreline north and south of the Dumbarton Bridge, but Bair Island, in San Mateo County, is also part of the system. The southernmost extent is in northern Santa Clara County.
