Mattaponi

thumb|Location of the Mattaponi Indian Reservation The Mattaponi () tribe is one of only two Virginia Indian tribes in the Commonwealth of Virginia that owns reservation land, which it has held since the colonial era. The larger Mattaponi Indian Tribe lives in King William County on the reservation, which stretches along the borders of the Mattaponi River, near West Point, Virginia.

The Mattaponi were one of six tribes inherited by Chief Powhatan in the late 16th century. The tribe spoke an Algonquian language, like other members of the Powhatan Chiefdom. The paramount chiefdom of the Powhatan numbered more than 30 tribes by the time the English arrived and settled Jamestown in 1607.
