Église Notre-Dame-de-Guadalupe, Roman Catholic church in Montreal, Canada

Notre-Dame-de-Guadalupe Church, formerly Sainte-Marguerite-Marie-Alacoque, stands at 1969 Rue Ontario Est at the corner of Rue Bordeaux in Ville-Marie. Its brick facade and walls incorporate neo-classical elements, and some stained glass was made by the French firm Rault et Frères. The organ, built in 1925 by the Compagnie d'Orgues Canadiennes, remains in place.

Father J. Arthur Graton founded the parish on Rue Ontario in 1923, entrusting construction to architects Ernest Cormier and Emmanuel-Arthur Doucet. The first stone was blessed on 24 August 1923; the church was inaugurated on 13 December 1925 and finished inside in 1926. Closed in 1991-1992, it became a Latin American parish dedicated to Our Lady of Guadalupe.

The parish was renamed for Our Lady of Guadalupe after closing in 1991-1992 and reopening as a Latin American church. Today about 2,000 people attend weekly, mainly at Sunday Mass. Four brotherhoods carry processions and devotions, among them the Hermandad del Señor de los Milagros and the Fraternidad del Divino Salvador del Mundo.

The church stands at 1969 Rue Ontario Est, at the corner of Rue Bordeaux, in the east of the Ville-Marie borough, near the Jacques-Cartier Bridge entrance. About 2,000 people attend each week, mostly at the Sunday mass, so weekday visits are quieter. A food-support team receives people every Wednesday.

The title "hundredth bell tower of Montreal" counts all places of worship open to the public on the island, chapels and conventual churches included, so it marks the hundredth Roman Catholic temple rather than the hundredth parish. Cardinal Jean-Claude Turcotte was baptised in this church.
