Grand Lake is a lake in central New Brunswick, Canada, approximately 40 kilometres east of Fredericton; and the province's largest freshwater lake. The lake drains through the Jemseg River and the Grand Lake Meadows into the Saint John River.

The lake is popular for recreation with locals, with several beaches and cottages on its shores.

Commercial barges of forest products were towed across the lake from a large sawmill in Chipman to a pulp mill in Saint John until the late 1990s. Other industrial activity around the lake includes New Brunswick's largest and currently only active coal mining area with extensive strip mines in the Newcastle Creek valley; a coal-fired power generating station, operated by NB Power, is located on the lake shore near the village of Minto.
