Kittery is a town in York County, Maine, United States. Home to the Portsmouth Naval Shipyard on Seavey's Island, Kittery includes Badger's Island, the seaside district of Kittery Point, and part of the Isles of Shoals. The town is a tourist destination known for its many outlet stores. It is the southernmost town in Maine.
Kittery is part of the Portland–South Portland–Biddeford, Maine metropolitan statistical area. The town's population was 9,490 at the 2010 census. Kittery may be the namesake of William Billings' 1783 anthem "Kittery", which is printed in the Shenandoah Harmony and Missouri Harmony shape note tunebooks, but because the song was published after the incorporation of the town, this is debated.
