Admiral Sir Edmund Nagle, KCB (1757 – 14 March 1830) was an Irish officer in Royal Navy during the late eighteenth and nineteenth centuries who is best known for his capture of the French frigate Révolutionnaire at the action of 21 October 1794 and his close association with George IV as a courtier from 1820 to his own death.

In 1770, Nagle entered the Royal Navy in the frigate Juno and was present at the British occupation of the Falkland Islands the following year.

He served in the American Revolutionary War without seeing extensive action, on Greenwich, Syren, Polecat, and Warwick until he was captured in 1782 when commanding the small brig Racoon.

He was recaptured in September by Warwick, and at the end of the war entered the reserve after briefly commanding Hound and Grana.

The squadron gave chase, Nagle catching the larger French ship and fighting her until support arrived.
