Jean-Francois Buisson de Saint-Cosme (1667–1706) was a Canadian missionary, born in Quebec, ordained in 1690, and murdered while on a missionary trip.
Jean-Francois came from a family with a high level of devotion to the Catholic Church. His brother Michel became a priest, a sister Marie-Francoise was a nun of the Hotel-Dieu, and an unidentified sister was a nun of the Congregation de Notre-Dame. His parents administered a farm for the seminary of Quebec at Ile Jesus. He was parish priest in Acadia from about 1692 until 1698 during the period of Joseph Robineau de Villebon and appears to have been less than successful in this pursuit.
Despite his lack of success in Acadia, Father St-Cosme become one of the pioneers of the missionary work by the Jesuits in the Mississippi Valley. By the end of 1704, he was alone in this work. He was murdered, with three French companions and a slave, while descending the Mississippi.
