Hans-Werner Kraus (1 July 1915 – 25 May 1990) was a German U-boat commander in the Kriegsmarine of Nazi Germany.

Kraus served as 1st watch officer on U-47 from January 1940 until November 1940 having replaced Engelbert Endrass.

He was on board the latter when it was attacked by Brazilian Air Force aircraft on 27 June 1943.

Kraus evaded only to be targeted by a VP-74 Mariner (BuNo 6571) piloted by Lt. Harold C. Carey.

Kraus was one of the 25 POWs who escaped from Camp Papago Park, Arizona, during the night of 23–24 December 1944 but was recaptured.
