Hartmut Haenchen (born 21 March 1943, Dresden) is a German orchestra conductor.

Haenchen began his musical career as a member of the Dresden Kreuzchor. By the age of 15, he was already conducting performances as cantor. As a 17-year-old, he attracted widespread attention with his revival of Johann Adolph Hasse's Requiem. Haenchen subsequently studied conducting and voice at the Dresden Hochschule für Musik. He then attended master classes in Berlin and at Carinthian Summer Festival in Austria, later attending rehearsals at the Bayreuth Festival and concerts conducted by Herbert von Karajan.

Haenchen's first engagement was as director of the Robert-Franz-Singakademie (choral society) in Halle and conductor of the Halle Philharmonic Orchestra in 1966. He went on to win first prize at the Carl Maria von Weber Competition in Dresden in 1971. In 1972-1973 Haenchen served as principal Kapellmeister of the Zwickau Theatre. During that period he made his debut at the Berlin State Opera, directing Mussorgsky's Boris Godunov. He appeared there regularly until 1986.
