Freischutz, Der, is an opera in three acts by the German composer Carl Maria von Weber (see Weber, Carl Maria von). The libretto (text), in German, was written by Friedrich Kind. It was based on a tale taken from Gespensterbuch (Book of Ghost Stories) written in 1811 by Johann Apel and Friedrich Laun. Three operas based on the same tale had already been written by other composers before Weber completed his. It received its first performance in Berlin on June 18, 1821.
