St. Joseph (French St-Joseph or Saint-Joseph) is a community in Huron County, Ontario, Canada, in the municipality of Bluewater.

It was first settled, as "Pointe-aux-Bouleaux", by some French Canadian families seeking greater opportunity in 1846.

Over the years the name was changed to "Johnson's Mills", "Lakeview" and finally "St. Joseph".

Narcisse Cantin is thought of as the "founder" of St. Joseph, having returned to the settlement from Buffalo in 1896 and being instrumental in his visionary yet failed attempt to better the community he grew up in.

However, the breakout of the First World War prevented work on the canal going forward.
