Kung Karls jakt is an opera with music by Fredrik Pacius and a libretto by Zacharias Topelius. It was the first opera to be composed in Finland and was in the style of Romantic nationalism. Kung Karls jakt was first performed in Helsinki on 24 March 1852. The text is in Swedish and concerns an event from Finnish history when Finland was a province of Sweden in the 17th century. The work takes the form of a Singspiel with spoken dialogue between the musical numbers. The music is heavily influenced by contemporary German and Italian opera, with a few Finnish elements such as the use of a kantele in one scene.
