Rybachy (Russian: Рыба́чий, from Рыба́к, "Fisherman", German: Rossitten, Lithuanian: Rasytė) is a rural settlement in Zelenogradsky District of Kaliningrad Oblast, Russia, located on the Curonian Spit.

Constantly threatened by coastal dunes the settlement had to be relocated several times until their migration was stopped by large-scale afforestation in the 19th century.

In 1924 the local gliding school became part of the Rhön-Rossitten Gesellschaft, predecessor of the Deutsche Forschungsanstalt für Segelflug (German Research Institute for Sailplane Flight).

It was transferred, along with the northern portion of the former province of East Prussia, to the Soviet Union in the aftermath of World War II.

Rybachy translates as "Fishers' (settlement)", and appropriately employment centers on the fishing boats which dock at the pier on the Curonian Lagoon.

In front of the church is a metal cross cast in 1992 by Eduardas Jonusas, an artist from the neighbouring Lithuanian town of Nida.
