The 2nd U-boat Flotilla (German 2. Unterseebootsflottille), also known as the Saltzwedel Flotilla, was the second operational U-boat unit in Nazi Germany's Kriegsmarine. Founded on 1 September 1936 under the command of Fregattenkapitän Werner Scheer, it was named in honour of Oberleutnant zur See Reinhold Saltzwedel. Saltzwedel, a U-boat commander during World War I, died on 2 December 1917, when his submarine UB-81 was sunk by a mine in the English Channel.
The flotilla was based in Kiel for the first few weeks after its formation, but was later moved to Wilhelmshaven, where it remained until May 1940. In June 1940, the flotilla was moved to Lorient in France until it was disbanded in August 1944.
