The lac Beauport is a body of water located north of Quebec, surrounded by the municipality of Lac-Beauport, in the La Jacques-Cartier Regional County Municipality, in the region of Capitale-Nationale, in the province of Quebec, in Canada.

It covers an area of 0.8 square kilometres (0.31 sq mi), at a maximum depth of 13 meters.

In recent years, the water in Lake Beauport was generally of very good quality and the parameters measured meet the quality criteria for the practice of recreational activities and the preservation of aquatic life, except for the level of aluminum, exceeding standards in 1999.

The main attractions are swimming, fishing for bass and speckled trout and boating.

In winter, the frozen surface of the lake hosts the Quebec Pond hockey Championship.
