James FitzJames, 1st Duke of Berwick (21 August 1670 – 12 June 1734) was a French Royal Army officer and nobleman who was the eldest illegitimate son of James II of England by Arabella Churchill, the sister of John Churchill, 1st Duke of Marlborough.

Born and raised in France, Berwick was a senior Jacobite commander in his father's army during the Williamite War in Ireland. He subsequently became a successful general in the service of Louis XIV and in 1706 he was made a Marshal of France. Berwick was honored with noble titles from the kings of both France and Spain, in addition to his English ducal title which was attainted in 1695. He was decapitated by a cannonball during the Siege of Philippsburg in 1734.
