Heinz Fiebig (23 March 1897 – 30 March 1964) was a German general in the Wehrmacht of Nazi Germany during World War II who may have been a recipient of the Knight's Cross of the Iron Cross of Nazi Germany.

Heinz Fiebig's nomination by the Heerespersonalamt (HPA—Army Staff Office) was ready for signature at the end of the war. According to the Association of Knight's Cross Recipients (AKCR) the award was presented in accordance with the Dönitz-decree. This is illegal according to the Deutsche Dienststelle (WASt) and lacks legal justification. The presentation date is an assumption of the AKCR.
