 
 This is a list of compositions by Felix Mendelssohn .
(Note: the list includes works which were published posthumously and given opus numbers after the composer's death. Only the opus numbers 1 to 72 were assigned by Mendelssohn, the later ones by publishers. The opus number sequence does not therefore always accord with the order of composition). The list also includes the Mendelssohn-Werkverzeichnis classification code (MWV).
