The Collegium Canisianum or simply Canisianum in Innsbruck, Austria, is an international School of Theology for priests' of the Roman Catholic church run by the Jesuits.^[1]

The Canisianum is one of many Jesuit seminaries worldwide named after Saint Peter Canisius and was built in 1910–1911 under Rector, or Regens, Michael Hofmann, to replace the previous Nicolaihaus seminary, which had been outgrown.^[2]

During World War I it also accommodated from 1915 to 1919 the students of the Collegium Germanicum in Rome.

On 21 November 1938 it was shut down by the National Socialists. The theology Faculty relocated to Sitten, Switzerland until they were able to return to Innsbruck in October 1945.^[3] In 2007 the Canisianum changed from a seminary to an International School of Theology, for ordained priests pursuing advanced studies at the University of Innsbruck.^[4]

Renovations were completed on the 100 year old building in 2022.
