The Gau Lower Silesia (German: Gau Niederschlesien ) was an administrative division of Nazi Germany from 1941 to 1945 in the Lower Silesia part of the Prussian Province of Silesia. The Gau was created when the Gau Silesia was split into Lower Silesia and Upper Silesia in 1941. The majority of the former Gau became part of Poland after the Second World War, with small parts in the far west becoming part of the future East Germany.
