Mihály Mosonyi (4 September 1815 in Boldogasszony, Hungary (now in Austria) – 31 October 1870 in Budapest) was a Hungarian composer. Born Michael Brand, he changed his name to Mosonyi in honor of the district of Moson (where his place of birth was located),[1] with Mihály being the Hungarian equivalent of "Michael". Like many of his peers, he was interested in creating a Hungarian musical style.

Mosonyi was primarily an instrumental composer, writing much piano music, especially of Hungarian character. His best-known works include Funeral Music, Benyovszky: The Exile of Kamchatka and Feast of Purification. He also composed a Piano Concerto in E minor (1844), two symphonies, five masses, three operas (the most famous is the Szep Ilonka), and chamber music (including seven String Quartets, a String Sextet, and two Piano Trios.).,[
