Bernhard Bästlein (3 December 1894 in Hamburg – 18 September 1944 in Brandenburg an der Havel) was a German Communist and resistance fighter against the Nazi régime.
He was imprisoned very shortly after the Nazis seized power in 1933 and was imprisoned almost without interruption until his execution in 1944, by the Nazis.
Nonetheless, he was one of the most important leaders of German Resistance.
