Gyönk (German: Jink) is a village in Tolna County, Hungary.

In 1947, a Czechoslovak-Hungarian population exchange saw 9 Highland Hungarian families (55 people) resettled in the upland village of Martos.

Until the end of World War II, the inhabitants' majority was Danube Swabian (Schwowe), whose ancestors had come from Swabia and Franconia.

[2] Only a few Germans of Hungary live there, the majority today are the descendants of Hungarians from the Czechoslovak–Hungarian population exchange.

The neo-Gothic style Lutheran Church designed by Gyula Reppmannin was completed in 1896.
