Fritz Krauss (born 20 March 1898 in Chur, Switzerland, died 13 July 1978 in Großhansdorf, Germany) was a German naval officer, most recently a Konteradmiral in the World War II.
Initially he continued his education at the Naval School and was subsequently watch officer on the light cruisers Arcona and Amazone.
As such, he remained aboard after the renaming of the Deutschland to Lützow, now reclassified as a heavy cruiser, and was appointed First Officer on 11 January 1940, taking part in Operation Weserübung, the invasion and occupation of Norway.
After its disbandment, Krauss was at the Oberkommando der Kriegsmarine between 1 December 1940 and 4 April 1941, before being appointed First Officer on the heavy cruiser Admiral Hipper.
From 16 August 1944 he was Chief of German Naval Intelligence Service and B-Dienst and was promoted to rear admiral a month later.
