Drusiliana was a civitas of Roman North Africa.
Bingham called it a city of the Roman province of Mauretania Caesariensis. An inscription of Constantine the Great was found in the city ruins and it appears on the Tabula Peutingeriana
The town has been tentatively identified with ruins near Khanguet-el-Kdim in northern Algeria.
Located at 36.249547N, 8.907667E. Epigraphical evidence suggest Constantine the Great undertook some works in the city in 312AD.
The town was also the seat of an ancient Christian bishopric, suffragan to Archdiocese of Carthage. This Bishopric is only known for the presence of bishops at the Council of Carthage, which saw gathered together Catholic bishops and Donatists of Africa: the Catholic side was represented by Rufino, while the Donatist by Restitutus.
The bishopric survives today as a titular see of the Roman Catholic Church. The current bishop is Yosyf Milyan of Kiev.
