HMS Babet was a 20-gun sixth-rate post ship of the British Royal Navy. She had previously been a corvette of the French Navy under the name Babet, until her capture in 1794, during the French Revolutionary Wars. She served with the British, capturing several privateers and other vessels, and was at the Battle of Groix. She disappeared in the Caribbean in 1800, presumably having foundered.

The action of 23 April 1794 took place between a British squadron of five frigates under the command of Sir John Borlase Warren and three frigates and a corvette under the command of Chef d'escadre F. Desgarceaux during the French Revolutionary Wars. Three of the French ships were captured.
