The Magog River, or Sekosonotek in Abenaki, is a river that drains Lake Memphremagog. It is a small river running through the territories of the cities of Magog and Sherbrooke, in the administrative region of Estrie, in Quebec, in Canada, along a southwest–northeast axis. Having its source in lake Memphremagog, it crosses lake Magog and empties into Saint-François River, in the city center of Sherbrooke.
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.
