Ambia was an ancient city in the Roman Empire, situated in present-day in Algeria. It is a modern titular see of the Roman Catholic Church. The colonia was located near the thermal baths of Hammam Bou Hani.
Bishopric
Ambia remains an ancient episcopal see of the Roman-Berber province of Mauritania Caesariensis. One bishop can be attributed to this office, Filece, who was among the Catholic prelates summoned to Carthage by the Vandal king Huneric in 484. Ambia survives today as a titular bishop; the current owner is Bishop John Migliorati, Apostolic Vicar of Awasa.
