German submarine U-75 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II. U-75 was moderately successful in her early career in the Battle of the Atlantic, but in autumn 1941 she was dispatched to the Mediterranean Sea with poor results, leading to the eventual destruction of the boat and her crew.
