André Grasset de Saint-Sauveur, fils was a Canadian-born Catholic priest who lived during the late 18th century. Born in Montreal in 1758, he moved to France as a child and was later ordained in Sens in 1783. He became a victim of the political upheaval in France, specifically due to his refusal to accept the Civil Constitution of the Clergy. After being held in the Carmes Prison, he was killed by guards in Paris in September 1792.
