Anbar (Arabic: الأنبار) was a town in Iraq, at lat. 33 deg. 22' N., long. 43 deg. 49' E, on the east bank of the Euphrates, just south of the Nahr 'Isa, or Sakhlawieh canal, the northernmost of the canals connecting that river with the Tigris.
Anbar was originally called Pērōz-Šāpūr or Pērōz-Šābuhr (from Middle Persian: 𐭯𐭥𐭩𐭥𐭦𐭱𐭧𐭯𐭥𐭧𐭥𐭩, meaning "Victorious Shapur"; in Parthian: 𐭐𐭓𐭂𐭅𐭆𐭔𐭇𐭐𐭅𐭇𐭓 prgwzšhypwhr; in Aramaic: פירוז שבור), and became known as Perisapora or Pirisabora to the Greeks and Romans. The city was founded c. 350 by the Sasanian Persian king Shapur II, and in the Sassanid province of Asōristān. Perisapora was sacked and burned by Emperor Julian in April 363, during his invasion of the Sasanian Empire. The town became a refuge for the Arab, Christian and Jewish colonies of that region. The name of the town was then changed to Anbar (Middle Persian word for "granaries"). According to medieval Arabic sources, most of the inhabitants of the town migrated north to found the city of Hdatta south of Mosul.
Anbar was adjacent or identical to the Babylonian Jewish center of Nehardea (Aramaic: נהרדעא), and lies a short distance from the present-day town of Fallujah, formerly the Babylonian Jewish center of Pumbedita (Aramaic: פומבדיתא).
Abu al-Abbas as-Saffah, the founder of the Abbasid Caliphate, made it his capital, and such it remained until the founding of Baghdad in 762. It continued to be a place of much importance throughout the Abbasid period.
Anbar used to host an Assyrian community from the fifth century: the town was the seat of a bishopric of the Church of the East. The names of fourteen of its bishops of the period 486–1074 are known, three of whom became Chaldean Patriarch of Babylon.

No longer a residential bishopric, having faded.
It has had the following incumbents, generally of the lowest (episcopal) rank, with a single archiepiscopal (intermediate) exception, the first :
- Titular Archbishop Stéphane Katchou (1980.10.03 – 1981.11.10), as Coadjutor Archeparch of Bassorah of the Chaldeans (Iraq) (1980.10.03 – 1981.11.10); later succeeded as Archeparch (Archbishop) of Bassorah of the Chaldeans (1981.11.10 – 1983.11.29), finally Archbishop-Bishop of Zaku of the Chaldeans (Iraq) (1983.11.29 – death 1987.11.08)
- Titular Bishop Ibrahim Namo Ibrahim (1982.01.11 – 1985.08.03), as Apostolic Exarch of United States of America of the Chaldeans (USA) (1982.01.11 – 1985.08.03); later restyled and promoted first Eparch (Bishop) of Saint Thomas the Apostle of Detroit of the Chaldeans (USA, the same) (1985.08.03 – 2014.05.03)

It is now entirely deserted, occupied only by mounds of ruins, whose great number indicate the city's former importance.
