The Bois-de-Liesse Nature Park is a large nature park that spans several cities on the northwestern part of the Island of Montreal in Quebec, Canada.

Most of the western reach of the park is in Dollard-des-Ormeaux, with a small part in Dorval.

The rest of the park spans the Montreal boroughs of Ahuntsic-Cartierville, Pierrefonds-Roxboro and Saint-Laurent.

The park is named after the Côte-de-Liesse, a former municipality that existed in the area, before being divided into Dorval, Lachine and Saint-Laurent in 1957.

The reception center is located in Pitfield House, which was built between 1952 and 1954 according to plans by the architectural firm Archibald, Illsley and Templeton.
