Deir ez-Zor, also spelled Deir Ezzor, Deir Al-Zor, Dayr Al-Zawr, Der Ezzor and other variants (Arabic: دير الزور; Syriac: ܕܝܪܐ ܙܥܘܪܬܐ, Armenian: Տէր Զօր, Դեր Զոր, Der Zor), is the seventh largest city in Syria and the largest in the eastern part of Syria. Located 450 km (280 mi) to the northeast from the capital Damascus on the shores of Euphrates River, Deir ez-Zor is the capital of the Deir ez-Zor Governorate. According to the 2004 official census, 211,857 people were residing in the city that year.
Among Syrians and neighbouring regions, Ad-Deir is used for short to indicate Deir ez Zor. The current name, which has been extended to the surrounding region, indicates an ancient site for one of the Early Christian secluded monasteries spread since the persecution times and Apostolic Age throughout Mesopotamia. Although Deir, which is Arabic for "monastery", thought to be kept throughout Medieval and Modern Age renaming, Zor, which indicates the riverbank bush, appeared only in some late Ottoman records.
The modern town was expanded by the Ottoman Empire in 1867 around the pre-existing town. In 1915, the city became a major destination point for Armenians subjected to death marches during the Armenian Genocide. A memorial commemorating the events was erected in the city in 1991. France occupied Deir ez-Zor in 1921 and made it the seat of a large garrison. Meanwhile, the region was locally ruled by Haj-Fadel Abboud, a member of an aristocratic family. In 1941 British-led forces defeated the Vichy French during the Syria-Lebanon campaign, which included a battle over Deir, and they handed administration of the region to the Free French. In 1946 it became part of the independent Republic of Syria.
Deir ez-Zor is situated 85 km (53 mi) to the northwest of the archaeological remains of Dura-Europos and 120 km (75 mi) northwest of the remains of the ancient city of Mari. During Roman times it was an important trading post between the Roman Empire and India. Conquered by Zenobia, it became part of the kingdom of Palmyra. After a successive wave of conquests, it was finally destroyed by the Mongols as they swept across the Middle East.

Since the discovery of light crude petroleum in the Syrian desert it has become a centre for the country's petroleum extraction industry. It is also a minor centre for tourism with many tourist facilities such as traditional French-style riverbank restaurants, up to 5-star hotels, a hub for trans-desert travel and an airport (IATA code: DEZ) in Al-Jafra suburb. There are salt mines nearby.
Deir ez-Zor was the final concentration place for Deir ez-Zor Camps for annihilating the Armenian deportation caravans. Tens of thousands of surviving men, women and children were systematically killed on the banks of the Euphrates River. Today the Armenian Genocide Memorial church commemorates the memory of Genocide victims who lost their lives.
Successive waves of new settlers from surrounding countrysides and provinces were heavily related to severe drought in late 1950s and 1990s most of them looking for standard jobs and giving away farming and herding life-style. Mesopotamian dialect of Arabic is used in the city, with slight influence of the North Syrian one can be noticed as well. Dominated by Sunni Muslims, Christianity in Deir ez-Zor can be traced back to the Apostolic Age, with few active churches and chapels belong to different congregations.
The city is also famous for the Deir ez-Zor suspension bridge (Arabic: الجسر المعلق) which spans the Euphrates and was completed in 1927.
