St. Petrus Canisius, Catholic church in Buchforst, Germany.

St. Petrus Canisius is a church in Buchforst with a basilica layout featuring high concrete beams and an elevated nave. Single-story side aisles flank the central space, and a square tower rises above the entrance portico.

St. Petrus Canisius was built in 1930–1931 to plans by Wilhelm Riphahn and Caspar Maria Grod as the centrepiece of the Weiße Stadt settlement, and consecrated on 15 February 1931. A first design was rejected by church authorities; the built version combines New Building forms with references to traditional church architecture. Much of the church was destroyed between 1942 and 1944 and rebuilt in 1948 by Gottfried and Dominikus Böhm, who bricked up the apse windows. It was listed as a monument in 1983.

The 1957 stained glass windows by Wilhelm de Graaff show scenes from the life of Saint Peter Canisius: the northwest side in red and green tones, the southeast side in blue. The remaining choir windows depict the twelve apostles. The church is dedicated to Canisius, a Jesuit who lived from 1521 to 1597.

The church is located at Eulerstraße 2 in Cologne's Buchforst district and serves the local Catholic community. It has been part of the St. Mauritius parish since 2006.

A 12-meter-high cross created by Heribert Calleen in 1962 crowns the tower. The five bells cast by Mabilon foundry in 1957 still ring from the structure.
