Captain John Deserontyon (alt. Captain John, Deseronto, (Odeserundiye)), U.E.L (c. 1740s - 1811) was a Mohawk war chief allied with the British during the American Revolutionary War. He led his people to Upper Canada after the war, settling on land granted by the Crown at the Bay of Quinte in present-day Ontario. This reserve, initially settled primarily by Mohawk loyalists from the Lower Castle, is known as Tyendinaga Mohawk Territory, Ontario. Deseronto, Ontario is named for him.
