Karl Diebitsch (3 January 1899 – 6 August 1985) was an artist and the Schutzstaffel (SS) officer responsible for designing much of the SS regalia during the Nazi era, including the chained SS officer's dagger scabbard.
Diebitsch worked with graphic designer Walter Heck to draft the well-known all-black SS uniform.
Also with his business partner, industrialist Franz Nagy, Diebitsch began the production of art porcelain at the factory Porzellan Manufaktur Allach.
