Fritz Reinhardt (3 April 1895, in Ilmenau – 17 June 1969, in Regensburg) was a state secretary in the German Finance Ministry in the time of the Third Reich.
At the outbreak of the First World War, Reinhardt was staying in Riga, Livonia, and he ended up spending the war in an internment camp in Siberia as an enemy alien. In 1919, he was the headmaster at the Thuringian Commercial School (Thüringische Handelsschule) and in 1924 founded the first German Long-Distance Commerce School. He was furthermore an administrator at the Thuringian State Finance Office.
In October 1926 (or in other sources 1924), he joined the Nazi Party and quickly built up a career with them with his talent for speaking and his knowledge of economic and taxation systems. In the same year, he became the Local Group Leader (Ortsgruppenleiter) in Herrsching, in 1927 the District Leader (Bezirksleiter) in Upper Bavaria-South, and in 1928 (and until 1930) the Upper Bavaria Gauleiter. From 1928 until 1933, Reinhardt was the leader of the Nazi Party's Speaking School. During this time, 6000 Party members received propagandistic schooling.
In 1930, Reinhardt became a member of the Reichstag and took on the leading role in the NSDAP in financial issues. In 1933, he became an SA Gruppenführer and a member of Adolf Hitler's Deputy Rudolf Hess's staff.
On 6 April 1933, after Hitler's intervention, Reinhardt became State Secretary in the Reich Ministry of Finance under Johann Ludwig Graf Schwerin von Krosigk succeeding Arthur Zarden, whose incumbency violated Nazi policy, as he was Jewish. In 1937 came Reinhardt's appointment as an SA Obergruppenführer.
