HMS Marlborough was a 74-gun third rate ship of the line of the Royal Navy, launched on 26 August 1767 at Deptford. She was one of the Ramillies class built to update the Navy and replace ships lost following the Seven Years' War. She was first commissioned in 1771 under Captain Richard Bickerton as a guard ship for the Medway. She served through two wars before her loss in 1800 when she struck a ledge of rocks off the Quiberon Peninsula; while she was pulled off the rocks, she was so seriously damaged that she foundered after all her complement were saved.[citation needed]
