Archelaïs was a town in the Roman province of Palaestina Prima, corresponding to modern Khirbet el-Beiyudat also known as Khirbet al-Bayudat. It was founded by Herod the Great's son Archelaus to house workers for his date plantation in the Jericho area. It is represented on the Madaba mosaic map with a towered entrance flanked by two other towers.
In Christian times, the town became a bishopric. The names of two of its bishops: Timotheus, who took part in two anti-Eutyches synods held in Constantinople in 448 and 449, and Antiochus, who was at the Council of Chalcedon in 451.
