Quercus incana is a species of oak known by the common names bluejack oak, upland willow oak, sandjack oak, and cinnamon oak. It is native to the Atlantic and Gulf coastal plains of the United States, from Virginia around Florida to Texas and inland to Oklahoma and Arkansas. The wood of Quercus incana is hard and strong, but the trees are usually too small to be good for any uses except fuel or posts. The acorns provide food for many animal species including the Sherman's fox squirrel, which lives in longleaf pine communities.
