Église Notre-Dame-du-Rosaire de Montréal, Catholic church in Villeray, Montreal, Canada.

Notre-Dame-du-Rosaire is a Catholic church in Villeray, Montreal, built 1928–1930 to plans by Dalbé Viau and Alphonse Venne. Its plan is a Latin cross with a projecting choir and a hemicycle apse. Inside, a Casavant organ with four keyboards, forty-five stops and 3,485 pipes was installed in 1932; the choir vault was painted by Guido Nincheri.

This is the parish's second church, replacing a brick and wood building from 1900. The crypt and foundation date from 1917; the church itself was built between 1928 and 1930 to plans by Dalbé Viau and Alphonse Venne. It was consecrated on 7 October 1984 by Paul Grégoire.

The church's name refers to the Rosary, and its interior holds works by several artists: sculptures by Bela Zoltvany (1891–1956), stained glass by Guido Nincheri and Vincenzo Poggi, and the chancel vault painted by Nincheri. The Casavant organ, installed in 1932, has four keyboards, forty-five stops and 3,485 pipes.

The church stands in Villeray, Montreal, and is reachable via Villeray Street. The Latin-cross plan with a projecting choir and hemicycle apse gives a clear orientation: the nave leads to the choir, where Nincheri painted the vault. The Casavant organ, with four keyboards, forty-five stops and 3,485 pipes, sits in the gallery.

The five bells in the towers were delivered in 1946 by the Paccard foundry of Annecy-le-Vieux, France. The church's Casavant organ, installed in 1932, has four keyboards, forty-five stops and 3,485 pipes. The choir vault was painted by Guido Nincheri, who also made stained glass with Vincenzo Poggi.
