Dülük (Armenian: Տլուք, romanized: Tlukʿ) is a neighbourhood in the municipality and district of Şehitkamil, Gaziantep Province, Turkey.

[5] It was ruled by the Kingdom of Commagene "for about 35 years";[6] after being governed by Antiochus Theos, it might have been incorporated into the Roman province of Syria as early as 31 BCE.

The worship of Jupiter Dolichenus became widespread from the mid-second to the mid-third century CE, particularly though not exclusively in the Roman army.

The University of Münster's Asia Minor Research Centre has been conducting excavation work at the main sanctuary of Jupiter Dolichenus under the direction of Engelbert Winter and Michael Blömer and is supported by the German Research Foundation (Deutsche Forschungsgesellschaft, DFG).

The international group consists of archaeologists, historians, architects, conservators, archaeozoologists, geoinformation scientists, and excavation workers.

The town, of strategic importance due to its location at the intersection of roads linking the major cities of the region, was conquered by Iyad ibn Ghanm during the first decades of the Muslim conquests.

[14] In the middle of the 10th century, it played a role in the conflict between resurgent Byzantium and the Hamdanid emirate of Sayf al-Dawla, and was retaken by the Byzantines in 962.

Doliche was an episcopal see, suffragan of the Metropolitan of Hierapolis Bambyce (capital of Euphratensis, in the civil diocese of Oriens), in the sway of the patriarchate of Antioch.
