The following is a list of compositions by the Russian composer César Cui. Titles of overall works are supplied in English unless the non-Russian original is distinctive in some way. Russian titles are added where helpful and applicable. Years in parentheses refer to the composition dates, not publishing dates. Complete listings of individual numbers within a larger work are not given, although certain well-known or recorded selections are cited. For important selections within an opera, go to the Wikipedia article for that opera, listed below and on the Wikipedia category-page for Cui's operas. Many individual compositions by Cui (primarily songs and choral pieces) have been published over the years, especially in English and French editions, without information as to opus number, if any. In order to avoid inaccuracy and unnecessary clutter, only those pieces that verifiably do not belong to an opus are included below along with the works with established opus numbers. (Note: Cui's compositions, especially from the end of his life, remain in manuscript in the Russian National Library; likewise with the full orchestral scores of several of the operas. The recent publications of the last of Cui's instrumental works (Opp. 104–106) has addressed the research gap in his unknown works.)
