HMS Cumberland was an 8-gun fire ship, previously the civilian vessel Alex Roberts.

She was purchased in 1739 and was broken up by 1742 after service in the War of the Austrian Succession.

Commissioned in July that year, she served under Commander Robert Maynard for operations in the Caribbean during the War of Jenkins' Ear.

Cumberland was present at Admiral Edward Vernon's attack on the port and defences at Chagres on 23 March 1740, and was later at the Battle of Cartagena de Indias in March and April 1741.

Cumberland was refitted at Woolwich Dockyard between September 1741 and January 1742, and then surveyed in February 1742.
