Lac-Matapédia (French pronunciation: [lak matapedja]) is an unorganized territory in the Bas-Saint-Laurent region of Quebec, Canada.

It is named after and located on the northern shores of Lake Matapedia in the Matapédia Valley.

The territory is home to a small protected area, Lac-Matapédia Forest Refuge (304 hectares (750 acres)) that was established in 2008 to protect three populations of the calypso orchid (Calypso bulbosa), a plant designated as threatened or vulnerable in Quebec.

[4] A part of the remainder of the territory is being considered for the creation of a new provincial park.
