Leningrad Mapping Unit (Ленинградская картографическая часть; 1943 - 1945), sometimes as Leningrad Military Mapping Unit (Ленинградская военно-картографическая часть), was a Soviet military cartographic unit which was created from the Soviet Military Topographic Service during the Second World War. It is best known for working during the latter stages of the Siege of Leningrad to produce a highly detailed Russian-language map of Berlin that was central to the Red Army's capture of that city in 1945.
