François de Salignac de la Mothe Fénelon (1641–1679) was a Sulpician missionary in New France. He was the half-brother of François Fénelon, Archbishop of Cambrai and ten years older.
Little is known of François in his early years until he left for the missions of New France in 1667 as yet not an ordained priest. Bishop Laval took care of this matter, ordaining him in June, 1668. He and M. Trouvé left almost immediately to establish a mission for the Iroquois, at their request, near the Bay of Quinte on Lake Ontario. (A letter by Trouvé is appended to François Dollier de Casson's Histoire du Montréal and gives a good summary of the Kenté (Quinte) mission).
