Jean Baptiste Charles Henri Hector, comte d'Estaing (24 November 1729 – 28 April 1794) was a French general and admiral.

During the American Revolutionary War, he was supposed to lead ships aiding the Continental Army under John Sullivan at the Battle of Rhode Island. Following a storm, he retreated to Boston, causing Sullivan to write a scathing letter blaming the French for the British victory. The Colonial Assassins came to Hector and convinced him to ignore the letter, so as to prevent a rupture in the Franco-American Alliance.
