HMS Sphinx (1748)

HMS Sphinx was a 24-gun sixth-rate frigate of the Royal Navy. The ship was built to the 1745 Establishment design drawn by the Surveyor of the Navy.

The ship was commissioned in September 1748 under Captain William Lloyd, and served in Nova Scotia until early 1750, before being refitted at Sheerness. She then moved to the Mediterranean, before returning to Home Waters in 1751, where she was briefly off Ireland. In late 1751, now under Captain Edward Wheeler, she was deployed to the African coast and thence to Jamaica. Returned to England, she was refitted at Deptford in 1755 and then recommissioned under Captain James Gambier for a fresh deployment to Jamaica. She returned to England in late 1758 under Captain John Dalrymple to pay off into reserve, seeing no further service until she was sold for breaking up in 1770.
