John Buck, titled Skanawati among other variants, was a leader of the Onondaga who lived near Ontario's Grand River. He was the official keeper of the wampum records of the Iroquois, sometimes described as a firekeeper. He took on the role of wampum keeper in 1843. Buck was described in a contemporary account as "a capable ruler and an able and trustworthy negotiator". Kenyon and Kenyon identify him as a "follower of Handsome Lake".
