John Abeel (ca. 1732–February 18, 1836), known as Gaiänt'wakê (Gyantwachia - ″the planter″) or Kaiiontwa'kon (Kaintwakon - "By What One Plants") in the Seneca language and thus generally known as Cornplanter, was a Seneca war chief and diplomat. As a chief warrior, Cornplanter fought in the French and Indian War and the American Revolutionary War. In both wars, the Seneca and three other Iroquois nations were allied with the British.
