'white', Greek: Άσπρος, Aspros) is a small town and seaside resort in Eastern Bulgaria, located on the Bulgarian Black Sea Coast in Varna Province.

Nature landmarks outside Byala include Karadere, one of Bulgaria's last remaining wild beaches with pristine dunes and freshwater wetlands, and the White Cliffs (Белите скали, Belite skali) displaying a classic Cretaceous–Paleogene boundary exposure; there is a demonstration centre.

In December 2007, plans were announced for a carbon-neutral resort at Karadere beach, some 3 km north of Byala, Norman Foster's first project in Bulgaria.

A series of car free hill towns in a setting of oak forests, meadows and river gorges, Black Sea Gardens will create a year-round community for up to 15,400 residents.

Due to the wilderness of the territory and lack of any infrastructure, the project needs huge investments and after assessment of these or maybe other reasons, the original investor has backed off (July 2008).
