Stephen Doutreleau (born in France, 11 October 1693; date of death uncertain, after 1747, in France) was a French Jesuit missionary who ministered to Native Americans and colonists in present-day Illinois, Mississippi and Louisiana for 20 years.
He became a Jesuit novice at the age of twenty-two and migrated in 1727 to Louisiana, with a group of Ursuline nuns.
In 1728 he was recorded at Post Vincennes, "the fort on the Wabash" [River], which was established about that time.
Two Jesuit missionaries, Paul Du Poisson (resident priest of Arkansas Post who had been visiting Natchez)[2] and Jean Rouel, were killed in these uprisings.
Ignorant of the hostilities and accompanied by four or five French voyageurs, Doutreleau landed at the mouth of the Yazoo River to offer up the Mass.
