The Magog River is a river that drains Lake Memphremagog. In turn, the river drains into the Saint-François River.

The cities of Sherbrooke and Magog, Quebec, lie on the Magog River.

Engineers from the Université de Sherbrooke have constructed a plastic bridge on the river.[citation needed][where?]
