HMS Lion was a 64-gun third-rate ship of the line of the Royal Navy, of the Worcester class, launched on 3 September 1777 at Portsmouth Dockyard.

[2] On 20 March 1780, Lion fought an action in company with two other ships against a French convoy off Monte Cristi, Dominican Republic, protected by Toussaint-Guillaume Picquet de la Motte's squadron.

Deprived of the ship that had landed them, Péron and his men spent some 40 months marooned on the island until Captain Thomas Hadley, in Ceres, rescued them in late 1795 and took them to Port Jackson.

In 1798, now under the command of Sir Manley Dixon, Lion fought a squadron of Spanish frigates at the action of 15 July 1798 and captured Santa Dorotea.

In July 1807 in the Malacca Strait she successfully protected from the French frigate Sémillante, without an engagement, a convoy homeward bound from China.

[10] In 1811, under the command of Captain Henry Heathcote, Lion was one of a large fleet of ships involved in the capture of Java from Dutch forces.
