Morceaux de fantaisie (French for Fantasy Pieces; Russian: Пьесы Фантазии, Pyesy Fantazii), Op. 3, is a set of five piano solo pieces composed by Sergei Rachmaninoff in 1892. The title reflects the pieces' imagery rather than their musical form, as none are actual fantasies. The set was dedicated to Anton Arensky, his harmony teacher at the Conservatory.
