Unterseebootsflottille), also known as Emsmann Flotilla, was a U-boat flotilla of Nazi Germany's Kriegsmarine during World War II.

The flotilla was formed in December 1938 in Kiel under the command of Korvettenkapitän Hans-Rudolf Rösing.

It was named in honour of Oberleutnant zur See Hans Joachim Emsmann, a U-boat commander during World War I, who died on 28 October 1918 after his U-boat UB-116 was sunk by a mine.

In 1946 Moehle was sentenced to five years in prison, after being found guilty of passing the Laconia Order to new U-boat commanders before they went out on patrol.
