Mussel Shoals is a coastal unincorporated community in Ventura County, California, between Ventura and the Santa Barbara County city of Carpinteria.
The community lies along U.S. Route 101 southeast of La Conchita and northwest of Faria. A one-lane causeway links the community with artificial Rincon Island.
Until the 1930s, the area from Bates Road down to Mussel Shoals (then known as Mussel Rock) was referred to as La Conchita.
