The Lemmensinstituut (Lemmens Institute) is a Belgian conservatory of music.
It was founded in Mechelen, in 1879, by the Belgian bishops as the École de musique religieuse (School of Religious Music).
Although its programs were greatly expanded over the years, it remained in essence a school of religious music until the 1960s and 1970s, when major changes occurred.
Nowadays the Lemmensinstituut has a reputation for offering one of Europe's finest Music Therapy degree programs.
The institute's Music Pedagogy course of study is also well known in Europe and in its history the Lemmens Institute has trained many famous composers including Jan van der Roost and Piet Swerts.
