Adolf Hühnlein (12 November 1881 Neustädtlein, Upper Franconia – 18 June 1942, Munich) was a German soldier and Nazi Party (NSDAP) official. He was the Korpsführer (Corps Leader) of the National Socialist Motor Corps (NSKK) from 1931 until his death in 1942.
Hühnlein was the son of a teacher. He married his wife Paula in 1906 and the couple had three children. He served in World War I, obtaining the rank of major. He had been decorated with the Iron Cross Second Class and First Class. After the war, he was a company commander in the Freikorps Epp. He joined the antisemitic nationalist group, the Bund Reichskriegsflagge (Imperial War Flag Society) and was involved in the Beer Hall Putsch—an unsuccessful attempt by Hitler and the NSDAP to seize power in Munich in November 1923. He was arrested for his role in the attempted coup and along with Hitler and other Nazi leaders was incarcerated at Landsberg Prison for high treason. This event would set Hühnlein on a life of Nazi politics and he rose through the ranks after being released from prison. He joined the Nazi Party and served in the Sturmabteilung (SA). Ernst Röhm appointed him an SA-Obergruppenführer and by 1927, Hühnlein was head of the SA automotive engineering.
Hühnlein was then appointed the leader of the National Socialist Automobile Corps (NSAK) which was to serve as a motorized corps of the SA. Thereafter, Hühnlein suggested the name be changed to National Socialist Motor Corps (NSKK). The name change became official on 1 May 1931. It was a paramilitary organization with its own system of paramilitary ranks and the smallest of the Nazi Party organizations.
