The Thompson River is a tributary of the south shore of De Montigny Lake, flowing in the town of Val-d'Or, in the La Vallée-de-l'Or Regional County Municipality, in the administrative region of Abitibi-Témiscamingue, in Quebec, in Canada.

Recreational tourism is the sector's primary economic activity, including pleasure boating on De Montigny lakes, Blouin and Lemoine Lake. This strait includes a marina.[1] (at south of the strait) and a seaplane base (in the middle of the strait). In addition, a railway bridge and a road bridge cross this strait which is located on the west side of the city of Val-d'Or.[2]

The surface of the Thompson River is generally frozen from mid-December to mid-April.
