Spud Island is a small island of the San Joaquin River, located in the Sacramento–San Joaquin River Delta in northern California. It was once used to farm onions; while it is no longer used for agriculture, it remains inhabited. In the late 20th century it was the site of a county park, which offered camping, fishing and swimming amenities free of charge.
