Hadrianopolis or Hadrianoupolis (Ancient Greek: Ἁδριανούπολις), was a town of ancient Epirus and Illyricum, founded by emperor Hadrian, and situated on the road from Apollonia to Nicopolis, about midway between those two towns.^[1] It was repaired and moved by Justinian I, and called Justinianopolis,^[2] and became one of the cities of the government of old Epirus and the see of a bishop.^[3] The small theatre and other vestiges in the plain below Libohovë mark the position of this city. Ten or twelve miles lower down the river are the ruins of a fortress or small town of the Byzantine age, called Dryinopolis. These remains are of a later age than the theatre, which belongs to Paganism. The probability is, that when Hadrianopolis fell into ruins Dryinopolis was built on a different site, and became the see of the bishop. Hadrianopolis in Epiro remains a titular see of the Roman Catholic Church.^[4]

Its site is located near Sofratikë, Dropull, in Albania.^[5][6]
