Fritz Brun (18 August 1878 – 29 November 1959) was a Swiss conductor and composer of classical music.
Brun was born in Lucerne. He was a student of Franz Wüllner at the conservatory at Cologne, and studied piano and theory there until 1902. The following year he became a piano teacher at the music school in Bern. From 1909 until 1943, he led the symphony concerts of the Bernischen Musikgesellschaft, and was conductor of the choral society and lieder group there. From 1926 to 1940, additionally, he was the vice-president of the Swiss music society Tonkünstlerverein. In June 1941 Brun retired, except for occasional returns to conducting. He dedicated his first violin sonata to violinist Adele Bloesch-Stöcker.
In 1912 Brun married Hanna Rosenmund; they had three children. Brun died in Grosshöchstetten.
