Little Island is a partially submerged marsh island in the Napa Slough, branching off from the Napa River upstream of San Pablo Bay (an embayment of San Francisco Bay). It is almost entirely in Napa County, California, although part of its southern tip is in Solano County; it is managed as part of the Napa-Sonoma Marshes Wildlife Area. Its coordinates are 38°10′48″N 122°21′05″W / 38.18000°N 122.35139°W / 38.18000; -122.35139 (Little Island), and the United States Geological Survey measured its elevation as 3 ft (0.91 m) in 1981.
