Témiscamingue (French pronunciation: [temiskamɛ̃ɡ]) is a regional county municipality in the Abitibi-Témiscamingue region of western Quebec, Canada.

The county seat is Ville-Marie.

[2] Though Témiscamingue borders Pontiac Regional County Municipality to the south, it is not practical to travel between the two within Quebec without taking a major detour north towards Quebec Route 117.

The shorter route is to cross into Ontario at Notre-Dame-du-Nord or Témiscaming and travel south on Highway 11, then east on Highway 17, before crossing back at L'Isle-aux-Allumettes.
