Magog is a city in southeastern Quebec, Canada, about 120 kilometres east of Montreal at the confluence of Lake Memphremagog—after which the city was named—with the Rivière aux Cerises and the Magog River. It is a major centre and industrial city in the Regional County Municipality of Memphremagog. The city lies in the Eastern Townships tourist region. In 2002 the City of Magog was merged with the Township of Magog and the Village of Omerville as part of the municipal reorganization in Quebec.
