Mayovka (Russian: Маёвка), prior to 1945 known by its German name Georgenburg (Lithuanian: Jurbarkas) was a rural locality in Chernyakhovsky District of Kaliningrad Oblast, Russia.
It was founded around the Ordensburg fortress Georgenburg ("George's castle") by the Teutonic Order.
The German-inhabited town became famous from a local stable for the Trakehner horse breed.
The town became a part of the Soviet Union in 1945 following World War II and was repopulated with Russians.
It was given its present name, which means a celebration of the International Workers' Day (May 1) in Russian.
