Franz Johannes Balthasar von Hößlin, also von Hoesslin (31 December 1885 in Munich – 25 September 1946 near Sète) was a German conductor. His second wife was the Jewish contralto Erna Liebenthal (1889–1946). The von Hoesslins went first to Florence, but when Benito Mussolini's Italy also presented problems, then moved to Geneva where Ernest Ansermet had invited von Hoesslin to conduct the Orchestre de la Suisse Romande.
