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.

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.

Hasso von Boehmer was won over to the plotters' cause by Tresckow, and he placed himself at their disposal as a liaison officer in the Wehrkreis ("Defence District") XX (Danzig – Gdańsk, Poland).

On the day of the attempt on Hitler's life at the Wolf's Lair in East Prussia, Hasso von Boehmer was accepting all the plotters' teleprinter messages which were reaching him from Berlin.

After the news spread that Hitler had survived the attempt, Hasso von Boehmer was arrested the very same day and taken to the prison on Lehrter Straße in Berlin.
