Friedrich Karl Florian (4 February 1894 in Essen – 24 October 1975 in Mettmann) was the Gauleiter of Düsseldorf in Nazi Germany.
He worked as Gauleiter of the Düsseldorf Gau from 1 January 1930 to 8 May 1945 – eight days after Adolf Hitler's death.
During this time, he was also a member of the Reichstag. On 1 May 1936, he was appointed to the Reich leadership. On 25 September 1933 he became an SA Gruppenführer, and on 30 January 1937 an SA Obergruppenführer.
In the final phase of the war, Florian kept sending people to their deaths, including minors of the Hitlerjugend. He never showed any remorse for his crimes.
