Tresco was a fifth-rate warship of the Commonwealth of England's naval forces, one of three such ships captured from Royalist forces during 1651 (the other two were and ). She was formerly the Royalist Michael, captured from them in the Isles of Scilly during the spring.
She was commissioned in 1651 under Captain William Blake and sent as part of a fleet to reduce the Channel Islands (which had stayed loyal to the Royalist cause). After bombarding shore positions in St Aubin's Bay, Jersey, the Tresco struck a submerged rock and foundered with heavy loss of life.
