Ste. Genevieve Township is a subdivision of Ste. Genevieve County, Missouri, in the United States of America, and is one of the five townships located in Ste. Genevieve County.

The township was named for the city of Ste. Genevieve, which in turn was named for the Catholic saint Genevieve, the patron saint of Paris.

The area of Ste. Genevieve Township was the site of the earliest European settlement in Missouri dating back to the early 1700s. The French colonial settlers partially came from Lower Louisiana, Quebec in Canada, and France. These Creole Habitants farmed the rich bottomlands along the Mississippi River, particularly the Grand Champ bottom, while coureur des bois trapped and traded furs. The local economy provided food and goods for the needs of the Upper Louisiana colony and New Orleans. Transportation to New Orleans was made by boat, while local transportation moved on local roads or traces. The King's Road or Kingshighway (French: le Chemin du Roi or Rue Royale) was begun in 1779 and connected the communities and outposts on the west bank of the Mississippi River. The area known today as Ste. Genevieve Township was split between two French colonial districts: Ste. Genevieve District and New Bourbon District. Upper Louisiana was transferred to the United States in 1804, and in 1824 the state of Missouri was carved from the territory. With the creation of Missouri subsequently came the establishment of Ste. Genevieve County. Ste. Genevieve Township was one of two original townships in the county.
