HMS Thetis (1773)

HMS Thetis was a 32-gun fifth-rate frigate of the Royal Navy, built by Wyatt & Co. at Buckler's Hard shipyard in 1773.

From 1777 to 1781 she served with the North American squadron. In January, 1778 she was under the command of Capt. John Gell.

Thetis took part in the action of 9 August 1780, when a convoy she was escorting fell prey to a Franco-Spanish squadron. 55 merchantmen were captured, but she managed to escape.

In 1780, she was wrecked.
