Stanisław Moniuszko (May 5, 1819, Ubiel, Minsk Governorate – June 4, 1872, Warsaw, Congress Poland) was a Polish composer, conductor and teacher. He wrote many popular art songs and operas, and his music is filled with patriotic folk themes of the peoples of the former Polish-Lithuanian Commonwealth (predominantly the Poles, Lithuanians and Belarusians).

He is generally referred to as the father of Polish national opera.
