Johann Friedrich Fasch (April 15, 1688 – December 5, 1758) was a German composer. He was born in Buttelstädt, was a choirboy in Weissenfels and studied under Johann Kuhnau at the Thomasschule in Leipzig (he later founded a Collegium Musicum in the city). He then traveled throughout Germany, becoming a violinist in the orchestra in Bayreuth in 1714, and also holding court posts in Greiz and Lukavec. In 1722 he was appointed Kapellmeister at Zerbst, a post he held until his death.
