The Raccoon Strait is a waterway of the San Francisco Bay between Angel Island and the Tiburon Peninsula, mainland Marin County, California, United States. During the ice ages, when sea levels were considerably lower and San Francisco Bay was a grassy valley, the combined Sacramento-San Joaquin river flowed through what is now Raccoon Strait before flowing through the canyon at the Golden Gate.
