This is a list of compositions by Olivier Messiaen. Works are listed initially by genre and can be sorted chronologically by clicking on the "Date" header. Messiaen's compositions include works for chamber ensemble, orchestra, vocal music, music for piano and organ, as well as some of the earliest electronic music, with his use of the ondes martenot in several of his compositions.
