Admiral Sir Robert Barlow GCB (25 December 1757 – 11 May 1843) was a senior and distinguished officer of the British Royal Navy who saw extensive service in the American Revolutionary War, the French Revolutionary Wars and the Napoleonic Wars. He made his name in small ship actions, especially fighting French frigates, of which he captured three. In his later career Barlow served as comptroller of the Navy and was influential at the Admiralty right up to his death. Although born to a middle-class family, Barlow and his siblings made names for themselves and two of Barlow's daughters married into the naval aristocracy.
