HMS Malabar was a 74-gun third rate ship of the line of the Royal Navy, launched on 28 December 1818 at Bombay Dockyard. In 1843, the Malabar assisted in rescuing survivors of the USS Missouri fire while in Gibraltar. She was hulked in October 1848, eventually becoming a coal hulk, and renamed Myrtle in October 1883. The hulk was sold out of the navy in July 1905.
