The University of Königsberg (German: Albertus-Universität Königsberg) was the university of Königsberg in East Prussia. It was founded in 1544 as the world's second Protestant academy (after the University of Marburg) by Duke Albert of Prussia, and was commonly known as the Albertina.
Following World War II, the city of Königsberg (renamed Kaliningrad) was transferred to the Soviet Union under the terms of the 1945 Potsdam Agreement. The Albertina was closed and the remaining German population was expelled. Today, the Immanuel Kant Baltic Federal University claims to maintain the traditions of the Albertina.
