Autoroute 19, also known as Autoroute Papineau (Papineau Highway), is an autoroute in Quebec. It crosses the Rivière des Prairies via the Papineau-Leblanc Bridge, connecting the borough of Ahuntsic-Cartierville in Montreal and the Duvernay neighbourhood in Laval.

A super two highway exists in Bois-des-Filion, north of Route 344 and south of Autoroute 640, just north of Pont David, which runs on the Highway 19 right-of-way and is part of Route 335.

Autoroute 19 was signed along Papineau Avenue in Montreal between Autoroute 40 and Henri Bourassa Boulevard until 2011; however, it was not officially considered part of Autoroute 19 as it is a street.^[1] It was once envisioned that A-19 would extend to the Jacques Cartier Bridge, and run below surface level south of the Metropolitan Expressway, like the Decarie Expressway. An autoroute-grade limited access expressway exists between the southern end of the Jacques Cartier Bridge and the northern end of the limited access expressway portion Route 116/Route 112 in St. Hubert, that is otherwise unsigned. The 112/116 expressway from the Jacques Cartier Bridge approach (the southern end of A-19) to Quebec Autoroute 30 was to have been designated Quebec Autoroute 16.
