The Leda-class frigates, were a successful class of forty-seven British Royal Navy 38-gun sailing frigates constructed from 1805 to 1832. Based on a French design, the class came in five major groups, all with minor differences in their design. During their careers, they fought in the Napoleonic Wars and the War of 1812. Forty-five of the 47 were eventually scrapped; two still exist: HMS Trincomalee and HMS Unicorn.

HMS Trincomalee is a Royal Navy Leda-class sailing frigate built shortly after the end of the Napoleonic Wars. She is now restored as a museum ship afloat in the National Museum of the Royal Navy, Hartlepool, England.
