Karl Ristenpart (January 26, 1900 – December 24, 1967) was a German conductor.

Born in Kiel, Germany, he studied at the Stern Conservatory in Berlin and in Vienna. He was heavily involved in creating three orchestras in his lifetime, most notably the Chamber Orchestra of the Saar. With this group he created one of the earliest recorded collections of Bach's orchestral music. These recordings were made originally between 1954 and 1967 as Les Discophiles Français, Erato and Club Français du Disque releases in France and appeared then under license with various American labels (notably Nonesuch) on both LP and cassette.
