James Gambier, 1st Baron Gambier, English admiral and politician, 36th Commodore Governor of Newfoundland (d. 1833)
Admiral of the Fleet James Gambier, 1st Baron Gambier, (13 October 1756 – 19 April 1833) was a Royal Navy officer. After seeing action at the capture of Charleston during the American Revolutionary War, he saw action again, as captain of the third-rate HMS Defence, at the battle of the Glorious First of June in 1794, during the French Revolutionary Wars, gaining the distinction of commanding the first ship to break through the enemy line.

Gambier went on to be a Lord Commissioner of the Admiralty and First Naval Lord and then served as Governor of Newfoundland. Together with General Lord Cathcart, he oversaw the bombardment of Copenhagen during the Napoleonic Wars. He later survived an accusation of cowardice for his inaction at the Battle of the Basque Roads.
