Lake Massawippi is a freshwater lake in Memphrémagog Regional County Municipality in the Estrie region of Quebec, Canada. The Tomifobia River is the source of the lake at its southern tip, near the village of Ayer's Cliff, Quebec. In early records, the lake was also called "Lake Tomifobi". The current of the lake flows north, funneling into the Massawippi River at the village of North Hatley, Quebec on Massawippi's northern shore.
It is bordered by five municipalities: North Hatley, Hatley Township, the municipality of Hatley, Ayer's Cliff and Sainte-Catherine-de-Hatley.
