Kosse or Cosse was a quarter of western Königsberg, Germany. Its territory is now part of the Tsentralny District of Kaliningrad, Russia. Kosse was originally a fishing village under the control of Altstadt on the northern shore of the lower Pregel. It was bordered to the northwest by Ratshof, to the north by Mittelhufen, and to the east by Laak, Lizent, and the 17th century Königsberg fortifications. Peter the Great of Russia stayed overnight at the inn of Kosse in 1712. By 1804 it contained a modest Gasthaus visited by the city's upper class.
