Regierungsbezirk Königsberg was a Regierungsbezirk, or government region, of the Prussian province of East Prussia from 1815 until 1945. The regional capital was Königsberg (since 1946, Kaliningrad).
In 1808 during the Napoleonic Wars, East Prussia was divided into Regierungsbezirke Gumbinnen and Königsberg, comprising the western parts of the former Duchy of Prussia and the territory of the Prince-Bishopric of Warmia, annexed by Prussia in 1772. On November 1, 1905, the southern districts of the two regions were separated to create Regierungsbezirk Allenstein.
Regierungsbezirk Königsberg was dissolved in 1945 when East Prussia was partitioned between Republic of Poland and the Soviet Union (Kaliningrad Oblast) after World War II.
