Rolf Mützelburg (23 June 1913 – 11 September 1942) was a German U-boat commander during World War II and a recipient of the Knight's Cross of the Iron Cross with Oak Leaves of Nazi Germany.

Mützelburg joined the Reichsmarine of the Weimar Republic on 1 April 1932 as member of "Crew 32" (the incoming class of 1932).

[1] He spent five months commanding the school boat U-10 from June to November 1940 as part of 21st U-boat Flotilla,[2] receiving his first combat experience aboard U-100 under Joachim Schepke.

He was swimming in the Atlantic south-west of the Azores, and dived from the conning tower, but struck the deck head-first when the U-boat suddenly lurched in the swell.

The supply U-boat U-462 arrived the next day with a doctor on board, but too late, and Mützelburg was buried at sea on 12 September 1942.
