Ferdinand von Sammern-Frankenegg (March 17, 1897 – September 20, 1943) was an SS-Oberführer (senior Colonel) and the SS and Police Leader of the Warsaw area from 1941. He was in charge of the first offensive operation in the suppression of the Warsaw Ghetto Uprising on April 19, 1943. After the failed offensive, von Sammern-Frankenegg was replaced by Jürgen Stroop, court-martialed on April 24, 1943, and found guilty of "defending Jews". He was subsequently transferred to Croatia where in September he was killed in a Yugoslav partisan ambush near the city of Klasznic.
