Ahvaz (Persian: اهواز; [ʔæhˈvɒːz] ) is a city in the Central District of Ahvaz County, Khuzestan province, Iran, serving as capital of the province, the county, and the district. It is home to Persians, Arabs, Bakhtiaris, Dezfulis, Shushtaris, and others. Languages spoken in the area include Persian, Arabic, Luri and dialects such as Bakhtiari, Dezfuli and Shushtari.

Ahvaz is home to over 1.2 million people within its metropolitan area, including Sheybani. Census results suggest a steady increase in population. At the time of the National Census of 2006, the city had 969,843 inhabitants in 212,097 households; 1,112,021 people in 288,271 households in 2011; and in 2016 the census counted 1,184,788 people in 331,556 households.

The river Karun flows through the middle of the city. It is one of the two navigable rivers in Iran, alongside the Arvand Rud. Ahvaz has a long history, dating back to the Achaemenid period. In ancient times, the city was one of the main centers of the Academy of Gondishapur.

The original inhabitants of the Khuzestan province, the Khuzi, are the source of the name "Ahvaz".

Later the name was changed to Hormazd-Ardašēr (Persian: هرمزداردشیر Hormozd ardeshir) and it became abbreviated to Daravashir later, but as a matter of fact, it's not quite clear if this change was by the King Ardashir I, in 230 (cf. Encyclopædia Iranica, al-Muqaddasi, et al.) or by his grandson Hormizd I (according to the Middle Persian Šahrestānīhā ī Ērānšahr (shahrestān hā-ye Irānshahr).

The city had two sections; the nobles of the city lived in one part while the other was inhabited by merchants.

In the 19th century, "Ahvaz was no more than a small borough inhabited mainly by Sabeans (1,500 to 2,000 inhabitants according to Ainsworth in 1835; 700 according to Curzon in 1890)."

In the 1880s, under Qajar rule, the Karun River was dredged and re-opened to commerce. A newly built railway crossed the Karun at Ahvaz. The city again became a commercial crossroads, linking river and rail traffic. The construction of the Suez Canal further stimulated trade. A port city was built near the old village of Ahvaz, and named Bandar-e-Naseri in honor of Nassereddin Shah Qajar.

Oil was found near Ahvaz in the early 20th century, and the city once again grew and prospered as a result of this newfound wealth. From 1897 to 1925, the city of Ahvaz was in the hands of heshmatoddoleh Ghajar, who acted as governor and Sarhang Reza Gholi Khane Arghoon commander of Ghajari's army based in Khuzestan. Sheikh Khaz'al was recognized by Mozaffar ad-Din Shah Qajar as hereditary ruler of Mohammerah, Sardar Asad Bakhtiari as the most powerful leader of Khuzestan's Bakhtiaries. He had power and authority over most regions of Khuzestan, such as Dezful, Shushtar, Izeh, even Ahvaz and Amir mojahede bakhtiari in Ramhormoz and Behbahan. At this time, the newly founded Ahvaz was named Nâseri in honour to its founder Nassereddin Shah Qajar. Afterwards, during the Pahlavi period, it resumed its old name, Ahvaz. The government of the Khūzestān Province was transferred there from Shûshtar in 1926. The Trans-Iranian Railway reached Ahvaz in 1929 and by World War II, Ahvaz had become the principal built-up area of the interior of Khūzestān. Professional segregation remained well marked between various groups in that period still feebly integrated: Persians, sub-groupings of Persians and Arabs. Natives of the Isfahan region held an important place in retail trade, owners of cafes and hotels and as craftsmen.

Iraq attempted to annex Khūzestān and Ahvaz in 1980, resulting in the Iran–Iraq War (1980–1988). Ahvaz was close to the front lines and suffered badly during the war.

Iraq had pressed its claims to Khūzestān. Iraq had hoped to exacerbate ethnic tensions and win over popular support for the invaders. Most accounts say that the Iranian Arab inhabitants resisted the Iraqis rather than welcome them as liberators. However, some Iranian Arabs claim that as a minority they face discrimination from the central government; they agitate for the right to preserve their cultural and linguistic distinction and more provincial autonomy. See Politics of Khūzestān.

In 1989, the Foolad Ahvaz steel facility was built close to the town. This company is best known for its company-sponsored football club, Foolad F.C., which was the champion of Iran's Premier Football League in 2005.

In 2005 the city witnessed a series of bomb explosions. Many government sources relate these events to developments in Iraq, accusing foreign governments of organizing and funding Arab separatist groups. The Arab Struggle Movement for the Liberation of Ahvaz claimed credit for several of the bombings, including four bombs on 12 June 2005, that killed 8 people.

Gunmen killed at least 29 people in an attack on a crowd watching a military parade on 22 September 2018.
