German U-boat bases in occupied Norway operated between 1940 and 1945, when the "Kriegsmarine" (German navy), converted several naval bases in Norway into submarine bases. Norwegian coastal cities became available to the "Kriegsmarine" after the invasion of Denmark and Norway in April 1940.
 Following the conclusion of the Norwegian Campaign (June 1940), the occupying Germans began to transfer U-boats stationed in Germany to many Norwegian port cities such as Bergen, Narvik, Trondheim, Hammerfest and Kirkenes.
 Initial planning for many U-boat bunkers began in late 1940.
 Starting in 1941, the Todt Organisation began the construction of bunkers in Bergen and Trondheim.
 These bunkers were completed by Weyss & Freytagg AG between 1942 and 1943.
