Rothenstein was first a suburb of and then a quarter of northeastern Königsberg, Germany.
Its territory is now part of the Leningradsky District of Kaliningrad, Russia.
It was connected to Maraunenhof by the road Cranzer Allee and to Kummerau by Rothensteiner Straße.
A munitions explosion at Rothenstein's munitions factory caused the death of 200 workers on 10 April 1920; Friedrich Lahrs and Stanislaus Cauer designed a memorial in the nearby Gemeindefriedhof cemetery to honor the victims.
After the Soviet capture of Königsberg during World War II, the NKVD established an internment camp in Rothenstein.
