Qinnašrīn (Arabic: قنشرين, romanized: Qinnašrīn; Syriac: ܩܢܫܪܝܢ, romanized: Qennešrin, lit. 'Nest of Eagles'; Latin: Chalcis ad Belum; Ancient Greek: Χαλκὶς, romanized: Khalkìs) was a historical town in northern Syria. The town was situated 25 km (16 mi) southwest of Aleppo on the west bank of the Queiq (historically, the Belus) and was connected to Aleppo with a major road during Roman times.
Some scholars propose that the ruins of Qinnašrīn are located at al-Hadher to the east of the Queiq River, while Chalcis' location was at the modern Syrian village of Al-Iss, Aleppo Governorate to the west of the river. Others think that Qinnasrin has always been located at al-Iss from the Hellenistic to the Ayyubid period.
