St. Jean Baptiste is an unincorporated community recognized as a local urban district[2] in Manitoba.

It is located in the Rural Municipality of Montcalm along Highway 75, 40 km north of Emerson at the United States border, and 60 km south of Winnipeg.

The area was first settled by Métis families from St. Norbert, Manitoba; in 1878, French-Canadian families from the United States arrived in the area and purchased land.

The post office opened in 1877 and a parish and Canadian National Railway point were also part of the early development.

The community was originally called Grosse Pointe, then was renamed Mission de la Rivière aux Prunes, before receiving its present name from Archbishop Taché in 1872.
