Fritz Thiele (14 April 1894 – 4 September 1944) was a member of the German resistance who also served as the communications chief of the German Army during World War II.

Working closely with Chief of Army communications General der Nachrichtentruppe Erich Fellgiebel, he was part of the assassination attempt against Adolf Hitler on 20 July 1944.

He was responsible as part of the coup attempt in the effort to sever communications between officers loyal to Hitler and armed forces units in the field and from the communications centre at the Bendlerstrasse in Berlin; he relayed a crucial message from Fellgiebel to General Friedrich Olbricht and the other conspirators that the assassination attempt had failed but the coup attempt should still proceed.

He was condemned to death on 21 August 1944 by the Volksgerichtshof and hanged on 4 September 1944 at Plötzensee prison in Berlin.
