This is a complete list of compositions by Maurice Ravel, initially categorised by genre, and sorted within each genre chronologically in order of date the composition was completed. Catalogue "M" numbers were assigned by the musicologist Marcel Marnat according to date of composition. Arrangements by Ravel of his own works were assigned the "M" number of the original followed by a letter (a, b, c, etc.). Arrangements by Ravel of other composers' works or of "traditional" music were assigned a separate "MA" number, in order of date of arrangement.
Ravel left many works incomplete or unpublished at the time of his death. Many of these works remain in the collection of Ravel's heirs. These do not include numerous fugues Ravel wrote, many of which were written during his time in the Conservatoire de Paris. Below are a few significant unpublished works.
