St. Philippe is a former village in Monroe County, Illinois, United States. The settlement was founded in ca. 1723[1] by Frenchman, Philip Francois Renault, during the French colonial period. St. Philippe was strategically located near the bluffs that flank the east side of the Mississippi River in the vast Illinois floodplain known as the "American Bottom". The village was located three miles north of Fort de Chartres. Because of many decades of severe seasonal flooding, St. Philippe and the fort were both abandoned before 1765. After the British takeover of this area following their victory in the Seven Years War, many French from the Illinois country moved west to Ste. Genevieve, Saint Louis, and Missouri
