Admiral Sir John Borlase Warren, 1st Baronet GCB GCH PC (2 September 1753 – 27 February 1822) was a British Royal Navy officer, politician and diplomat.

Born in Stapleford, Nottinghamshire, he was the son and heir of John Borlase Warren (died 1763) of Stapleford and Little Marlow. He entered Emmanuel College, Cambridge in 1769, but in 1771 entered the navy as an able seaman; in 1774 he became member of Parliament for Great Marlow; and in 1775 he was created a baronet, the baronetcy held by his ancestors, the , having become extinct in 1689.
On the 12th of Dec. 1780 he married Caroline daughter of Lt.-Gen. Sir John Clavering. She died in 1839.

His career as a seaman really began in 1777, and two years later he obtained command of a ship. In April 1794, as Commodore of the frigate squadron off the north west French coast assisting in the blockade of Brest, Warren and his squadron captured a number of French frigates. In 1795, he commanded one of the two squadrons carrying troops for the Quiberon expedition and in 1796 his frigate squadron off Brest is said to have captured or destroyed 220 vessels. In October 1798, a French fleet — carrying 5,000 men — sailed from Brest intending to invade Ireland. The plan was frustrated in no small part due to the squadron under his command during the Action of 12 October 1798.
