Yasnaya Polyana is a rural settlement in the Nesterovsky District of Kaliningrad Oblast, Russia. It is located in the southeast of the oblast, north of the Romincka Forest. Nearby Diwnoje Nowoje is a railway station on the former Prussian Eastern Railway from Kaliningrad to Kybartai in Lithuania.
The settlement was originally known as the village of Trakehnen in East Prussia, named after the Old Prussian word trakis, meaning "great bog". In 1731 King Frederick William I of Prussia had the swampy territory of the Pissa River drained to establish the famous warmblood Trakehner horse breed stable northwest of the municipality. The area was colonized by Protestant expellees from the Archbishopric of Salzburg.
