Longuyon is a commune in the Meurthe-et-Moselle department in north-eastern France.
The apartment blocks on the southwestern edge of town, still called "La Cité Canadienne", were home to Royal Canadian Air Force staff and their families in the 1950s and 1960s, when the RCAF had an airbase at nearby Marville. The street names still carry the names Toronto, Montreal, etc., and a totem pole was erected as a monument to the Canadian presence in Longuyon.
