HMS Barham was a 74-gun third rate built for the Royal Navy in the first decade of the 19th century. Completed in 1812, she played a minor role in the Napoleonic Wars.
In 1826 Barham was reduced to a 50-gun ship. On 29 April 1829 she suffered severe damage when she ran aground off Bonaire; she was refloated on 30 April 1829 after her crew threw 37 cannon overboard. She was broken up in 1839.
