Bialystok-Grodno District () was an administrative subdivision of German-controlled territory of Ober-Ost during World War I (after the GorliceâÂÂTarnów Offensive). It was bordered by the Lithuania District to the north.
The area was formed roughly by parts of the occupied Grodno Governorate of the Russian Empire.
Initially, in 1915, the territory of the newly created Ober Ost administration was divided into six districts, headed by German administrators (governors), including: von Bockelberg in Bialystok and Theodor von Heppe in Grodno (the others were: Rüdiger von Haugwitz in Suvalki, von Beckerath in Vilna, Franz-Joseph zu Isenburg-Birstein in northwestern Lithuania (Kovno), and Alfred von Gossler in Courland).
In March 1917, regional administration was reorganized, dividing the entire Ober Ost into three districrs: Courland, Lithuania, and the united Bialystok-Grodno district.
In August 1918, the Bialystok-Grodno district was included into the enlarged Lithuanian district.
