Julius Burger (Bürger) (Vienna 11 March 1897 - New York City, 12 June 1995) was an Austrian then American composer, pianist and conductor.

He studied at the Vienna Academy of Music under Franz Schreker, and was one of the group of Schreker's pupils - Alois Hába, Jascha Horenstein, Ernst Křenek, Karol Rathaus - who followed Schreker to Berlin when Schreker was appointed Director of the Hochschule für Musik.

He had a long association with the Metropolitan Opera, New York first dating from his apprenticeship in 1924–1926, when Bruno Walter recommended him as assistant to Artur Bodanzky. He was an assistant to Otto Klemperer at the Kroll Opera, then following the Nazi ban on Jewish artists in 1933, drifted between Vienna, Brussels and Paris as well as visits to London to work for the BBC as an orchestrater. In February 1938 Bürger and his wife exited a train to Vienna in Paris, and in 1939 they departed permanently for America. His mother and five of his brothers were sent to Auschwitz, his mother being shot by the roadside and the brothers murdered in the camp.
