The Massawippi River is a river flowing in the territory of North Hatley (MRC de Memphrémagog) and the city of Sherbrooke, in the administrative region of Estrie, in Quebec, Canada.

The name Massawippi could come from the Algonquin term nasawipi which means "between the waters".

Although the two versions may exist, several places in the area are named by the words used by the Abenaki such as Magog, Lake Memphremagog, Coaticook and Mégantic.

From the North Hatley Bridge at the mouth of Lake Massawippi, this river flows over 19.0 kilometres (11.8 mi), with a drop of 10 metres (33 ft) according to the following segments: The confluence of the river with the Saint-François River was called “petite fourche” (little fork) by the Abenakis, French missionaries and the first settlers, before being known under the name of Lennoxville.
