Gerhard Wagner (18 August 1888 – 25 March 1939) was the first Reich Doctors' Leader (Reichsärzteführer) in the time of Nazi Germany.

Born a surgery professor's son, he studied medicine in Munich and served as a doctor at the front in World War I (1914–1918).

From 1919, Wagner ran his own medical practice in Munich, while also being a member of two Freikorps between 1921 and 1923, von Epp and Oberland.

Wagner was co-founder and as of 1932 leader of the National Socialist German Doctors' League, and also functioned from 1933 as a member of the Palatinate Landtag.

As was typical of Nazi propaganda at this time, this was more in terms of the pure and growing race than the evil of the Jews.
