The National Socialist Flyers Corps (German: Nationalsozialistisches Fliegerkorps; NSFK) was a paramilitary organization of the Nazi Party that was founded April 15, 1937 as a successor to the German Air Sports Association; the latter had been active during the years when a German air force was forbidden by the Treaty of Versailles. The NSFK organization was based closely on the organization of the Sturmabteilung (SA) and maintained a system of paramilitary ranks closely associated with the SA. A similar group was the National Socialist Motor Corps. During the early years of its existence, the NSFK conducted military aviation training in gliders and private airplanes.
General der Flieger Friedrich Christiansen was NSFK Korpsführer from April 15, 1937 until June 26, 1943, followed by Generaloberst Alfred Keller until May 8, 1945.
