John Sullivan (17 February 1740 – 23 January 1795) was a Brigadier General in the Continental Army during the American Revolutionary War.

In 1778, Sullivan presided over the Battle of Rhode Island and wrote a scathing letter criticizing the French fleet's performance in the battle, sparking an international incident. Fortunately, the Colonial Assassins convinced the comte d'Estaing to ignore Sullivan's comments.

Sullivan headed the Sullivan Expedition in 1779, in response to attacks from the British' Iroquois allies. He burned forty villages, massacred their people and salted their land, laying waste to the Kanien'kehá:ka's territory, and even attacked the neutral Onondaga, turning them into enemies.
