Durankulak (Bulgarian: Дуранкулак [doˈrankoɫak]) is a village in northeastern Bulgaria, part of Shabla Municipality, Dobrich Province.

The village lies on an elevation of 26 metres above mean sea level, on the E87 littoral road, 6 kilometres south of the Romanian border.

Hamangia people were small-scale cultivators and plant collectors who built houses made pottery and herded and hunted animals.

It was abandoned in the middle of the 19th century and had around 200–300 residents, but its location meant the danger of malaria made it unsuitable for living in the summer.

On 1 June 1900, the village was the centre of an peasant revolt against the government of Todor Ivanchov and as a result, 90 people were killed by the national cavalry.

[3] Between 1913 and 1940, it was under Romanian rule along with all of Southern Dobruja and was renamed to Răcari, but it was returned to Bulgaria according to the Treaty of Craiova.

From its return to Bulgaria to 1963, the village was known as Blatnitsa (Блатница, "marshy place"), but its historic name was reinstated to commemorate the revolt of 1900.

The name is of ancient origin meaning the place where the taurus knocked with his fist (hoof) and gushed water surrounded the two isles in the lake.

Among the important birds in the area are the little bittern, ferruginous duck, mute swan, western marsh harrier, paddyfield warbler.
