Hasso von Boehmer (9 August 1904 – 5 March 1945) was a German lieutenant colonel on the General Staff and one of the 20 July Plotters. Hasso von Boehmer belonged to Infantry Regiment 9 (I.R. 9) from Potsdam, from which also came many of the other plotters. They served, among others, Major General Henning von Tresckow and Fritz-Dietlof von der Schulenburg in the regiment. All together, I.R. 9 supplied more plotters for the attempted assassination of German dictator Adolf Hitler and abortive coup d'état than any other regiment in the Wehrmacht.
