Earl of Tankerville is a noble title drawn from Tancarville in Normandy. The title has been created three times: twice in the Peerage of England, and once (in 1714) in the Peerage of Great Britain for Charles Bennet, 2nd Baron Ossulston. His father, John Bennett, 1st Baron Ossulston, was the elder brother of Henry Bennett, 1st Earl of Arlington. The family seat was Chillingham Castle in Northumberland.
The Earl of Tankerville holds the subsidiary title of Baron Ossulston, of Ossulston in the County of Middlesex (1682), in the Peerage of England.
The heir presumptive is the present holder's cousin, Adrian George Bennett (b. 1958).
