The Symphony in A minor "Odense", K. Anh. 220/16a/Anh.C 11.18, was formerly attributed to Wolfgang Amadeus Mozart. If the Odense Symphony had truly been Mozart's, it would be among only three of Mozart's symphonies (along with the G minor symphonies, No. 25 and No. 40) to be written in a minor key. It is now considered certain that the symphony is not by Mozart.
