This list includes all the works that Sibelius is known to have completed. It also includes works which he planned to revise but never did (see for example op. 6 Cassazione). In addition to the official names of the works, the most frequently used English names are given. The information on the first performance is only given for the orchestral works and incidental music, since this information is not available for most of the minor works.
