The Accohannock (also known as Accohanoc and Annamessex ) are a Native American tribe. They lived in Virginia, including the counties of Accomack and Northampton in Virginia, in the United States. They may have been members of the Powhatan Confederacy. however they do not seem to have ever referred to themselves as "Annemessick". There is no documentary evidence that "Occohannock" territory extended as far north and west as the Annamessex River in what is present-day Maryland in pre-Contact or Contact times. Instead, the limited documents indicate that the "Annamessex Indians"—which is how the residents are called—were allied with the Pocomokes.
