The lac Honorine is a freshwater body on the hydrographic side of the Launière River, of the Jacques-Cartier River, in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province, in Quebec, Canada.

The area around the lake is indirectly served by the route 175 which passes on the east side. A few secondary forest roads serve this area for forestry and recreational tourism purposes.

Forestry is the main economic activity in the sector; recreational tourism, second.

The surface of Lake Honorine is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.
