The International Mozarteum Foundation (Internationale Stiftung Mozarteum) was founded in 1880 in Salzburg with its primary concern being the life and work of Wolfgang Amadeus Mozart.
It was preceded by the Cathedral Music Association and Mozarteum of 1841 and is closely affiliated with the Mozarteum University of Salzburg.
It collects Mozart memorabilia, maintains the Mozart library (the Bibliotheca Mozartiana), the Mozart birthplace and other Salzburg locations linked with Mozart.
Among other concerts, it presents an annual Mozart Week Festival of performances of the composer's works coinciding with his birthday around 27 January. The festival is regarded as an artistic highlight in the European concert calendar. The Foundation presents up to twenty other performances year-round.
The foundation also promotes research regarding Mozart.
It administers various awards such as the Mozart Medal, the Preis der Internationalen Stiftung Mozarteum and the Lilli Lehmann Medal.
