Joseph Louis Cook, or Akiatonharónkwen (died October 1814) (Mohawk), was an Iroquois leader and commissioned officer in the Continental Army during the American Revolution. Born to an African father and an Abenaki mother in what is now Schuylerville, New York, he and his mother were taken captive in a French-Mohawk raid and taken to Kahnawake, a Mohawk village south of Montreal. They were adopted by a Mohawk family. His mother soon died and he served Catholic missionaries, learning French. He became an influential leader among the Mohawk and distinguished himself as a warrior for their allies the French during the French and Indian War.
