Église Saint-Stanislas-De-Kostka, Catholic parish church in Montreal, Canada.

Église Saint-Stanislas-De-Kostka is a Romanesque Revival church built in 1910–1912 to plans by architect Louis-Alphonse Venne. Its walls are entirely stone and its roof copper; the interior has a three-aisle nave, a baptistery, two tribunes and an outdoor chapel. The building covers about 6,000 square metres.

The parish was founded on 16 June 1910 by Bishop Paul Bruchési, replacing a chapel the Jesuits of the Immaculée-Conception parish had built a few years earlier and already dedicated to Saint Stanislaus Kostka. Work on the church ran from 1910 to 1912; a fire on 19 December 1917 badly damaged the building, which had to be rebuilt. The first pastor was Abbé Vincent Piette, also rector of the Université de Montréal.

The church is open to visitors for masses and community events throughout the year. Plan your visit around the regular services and religious celebrations held here.

The organ, built by Casavant Frères in 1920, has 54 stops and 3 manuals and was restored in 1987. The first stained-glass windows were made by O'Shea and Perdriau, and more were added in 1929 by Guido Nincheri. The interior paintings are by the Carle et Petrucci firm.
