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.
