Balka, also Balke, is a village and seaside resort midway between Nexø and Snogebæk on the southwest coast of the Danish island of Bornholm.

[2] The current name "Balka" ending with an A is incorrect as the locality was originally called "Balke" as can be seen on Bernhard Frantz Hammer's map from 1746.

The fine sand from the sandstone rocks of neighbouring Nexø has filled Balke Bay and formed low sand-dunes.

Similarly, the large boulders deposited on the beach while building summer houses on the dunes has caused the sand to be washed away.

[6] A short distance inland from Balka, the Hundsemyre bird sanctuary attracts in particular the penduline tit and the great cormorant.
