Mayakovskoye (Russian: Маяко́вское), previously known in German as Nemmersdorf (Lithuanian: Nemirkiemis), is a rural locality (a settlement) in Gusevsky District of Kaliningrad Oblast, Russia, located on the banks of the Angrapa River.
Until 1945, Nemmersdorf was a part of German East Prussia. It became known during World War II on October 22, 1944 as the site of the first Soviet war crime on German territory against German women, French and Belgian POWs—the Nemmersdorf massacre.
The first documented mention of Nemmersdorf was in 1515 in a decree of the Insterburg Central Office. By 1910, it counted a total of 484 residents, further increasing to 637 by 1939. Between 1874 and 1945, Nemmersdorf was the principal urban locality in Gumbinnen administrative district within the county of Nemmersdorf-Gumbinnen in East Prussia. The municipality included thirteen rural communities.
