Lieutenant Gillette (portrayed by Damian O'Hare) is a minor character in Pirates of the Caribbean films.
He is Commodore Norrington's Flag Lieutenant and second-in-command in Port Royal. He is left in H.M.S. Dauntless during Norrington's absence and loses the ship to Jack Sparrow. He accompanies Commodore Norrington on the Dauntless in pursuit of both the Black Pearl and the Interceptor. When they rescue Elizabeth, she warns Lieutenant Gillette about the curse of the pirate crew aboard the Black Pearl but he refuses to believe her. When the cursed pirates ambush the Dauntless, Gillette, who was left in charge of the Dauntless at the time, fights off the cursed pirates with the remainder of his crew before Norrington and his Royal Marines arrive to reinforce the dwindling resistance against the pirates. He survives the final battle of Curse of the Black Pearl. It was at first believed that he perished during Norrington's ill-fated pursuit of Jack Sparrow between the events of Curse of the Black Pearl and Dead Man's Chest, but he returns unharmed in On Stranger Tides as Captain Barbossa's third-in-command aboard the H.M.S Providence. He assists Barbossa in claiming the Fountain of Youth before Blackbeard and the Spaniards do. He was killed in a duel with Blackbeard by Blackbeard's sword.
