What it means
استان (ostân) is the word for province in Iran’s official administrative system. Iran is divided into thirty-one استان, each governed by a governor-general appointed by the central government in Tehran. The word descends from Middle Persian ostân, meaning district or settled region, and was consciously revived during the Pahlavi era as part of a broader effort to replace Arabic-derived administrative vocabulary with native Persian alternatives. The plural is استانها (ostânhâ). A related term is شهرستان (shahrestân), the subdivision inside a province, equivalent to a county or district.
How to use it
- ایران سی و یک استان داره. (Irân si o yek ostân dâre.) “Iran has thirty-one provinces.”
- من از استان فارس هستم. (Man az ostân-e Fârs hastam.) “I am from Fars Province.”
- مرکز استان خوزستان اهوازه. (Markaz-e ostân-e Khuzestân Ahvâze.) “The provincial capital of Khuzestan is Ahvaz.”
- استانهای شمالی ایران سرسبزترن. (Ostânhâ-ye shomâli-ye Irân sarsabztaran.) “The northern provinces of Iran are greener.”
Cultural note
Iran’s thirty-one provinces vary enormously in size, population, climate, and ethnic composition. Provinces like Gilan and Mazandaran on the Caspian coast are densely forested and rainy, while Sistan and Baluchestan in the southeast is one of the driest and most remote regions in the country. Knowing which استان a person is from often signals their native dialect, cuisine, and cultural background. Province names appear constantly in everyday conversation, news, and personal introductions, making استان one of the most practically useful geographic words a Farsi learner can acquire.
