Jacques Buteux (11 April 1600 – 10 May 1652) was a French-born Jesuit who became a missionary in Canada.
Buteux came to Canada in 1634 and was assigned to Trois-Rivières, where he ministered until his death in 1652. His death took place during a mission journey. His party was attacked by a troop of Iroquois lying in ambush. He was shot and tomahawked. Father Buteux had left letters and many documents in the parish registers giving historians a good profile of his time in Canada.
