The St. Clair River ( also Saint Clair River; French Rivière Sainte -Claire ) is 64 km long and part of the 3776 km long St. Lawrence Seaway.

The St. Clair River connects the upper and lower Great Lakes. It flows in a southerly direction from the south shore of Lake Huron to Lake St. Clair. In the mouth area it is divided into various estuaries and makes a great river delta.

The river forms its entire length part of the border between the U.S. and Canada, with its western shore of Michigan and Ontario on the eastern shore.

The river was named after Arthur St. Clair.
