Sayenqueraghta (c. 1707 – 1786) was the war chief of the eastern Seneca tribe in the mid-18th century. His name in the Seneca language is phonetically rendered as Kaieñãkwaahtoñ, and was spelled in a variety of ways, including Gayahgwaahdoh and Kayenquaraghton. In historical records he is most often known as Sayenqueraghta (or Sayengaraghta), which was his name in the Mohawk language, or by nicknames such as Old Smoke or the Seneca King. He was called Old Smoke because he held the official position as the "smoke-bearer".
He was born the son of a prominent Seneca chief of the Turtle clan in western New York. He lived most of his life at Ganundasaga, near the present day town of Geneva, New York. He obtained his rank of war chief in 1751. Before the American Revolution he was referred to as chief of the Senecas.
During Pontiac's Rebellion he was the Seneca war-chief who defeated the British at the Battle of Devil's Hole. A portion of the Seneca fought the British during Pontiac's Rebellion of 1763. In 1764 the Seneca came to Fort Niagara where they made peace and Sayenqueraghta "buried the Axe".
In 1765, he along with Handsome Lake and about one hundred other Seneca warriors went on an expedition against the Cherokee and Choctaw. This expedition was remembered nearly a century later for the loot of scalps and other trophies obtained.
Early in the American Revolution, Sayenqueraghta tried to keep the Iroquois neutral. He attempted in June, 1777 to retrieve Seneca warriors who had joined Butler at Fort Niagara. In July, 1777, the Iroquois decided to enter the war on the British side and he was named, along with Cornplanter, to be the war chiefs of the Iroquois confederacy.
He was one of the organizers of the ambush at the Battle of Oriskany, where his son was killed. He was the primary Indian leader at the Battle of Wyoming. His village of Ganundasaga was destroyed during the Sullivan Campaign and was not rebuilt. Sometime before 1781 he and his family relocated to Buffalo Creek, near Fort Niagara. In 1779, he started receiving a pension from the British of one hundred dollars per year. He resented the favourable treatment the British gave to Joseph Brant. Sayenqueraghta was at the Battle of Johnstown and other battles. In 1781, he led a war party towards Fort Pitt.
He was described by General Frederick Haldimand as "by many degrees the most leading and the man of most consequence and influence in the Six Nations". In 1783, a British Officer said "He is a sensible old man and has been a very good warrior in his day, but like the rest is very much addicted to liquor".
