The Appomattoc (also spelled Appamatuck, Apamatic, and numerous other variants) were a historic tribe of Virginia Indians speaking an Algonquian language, and residing along the lower Appomattox River, in the area of what is now Petersburg, Colonial Heights, Chesterfield and Dinwiddie Counties in present-day southeast Virginia.
The Appomattoc were affiliated with the estimated 30 tribes of the Powhatan Confederacy, who controlled the area then known as Tenakomakah, present-day Tidewater Virginia. According to William Strachey, the Appomattoc were one of four subtribes within the original inheritance of Chief Powhatan, before he incorporated the other tribes into his Confederacy, and were said to be closely connected with the Powhatan royal line.
