The aviation sector in Iran is supervised by the Iran Civil Aviation Organization (CAO), a governmental agency under the Ministry of Roads and Urban Development. The CAO is responsible for regulating, overseeing, and developing Iran's civil aviation industry and ensuring its safety and security.

Several private companies operate in the aviation sector, such as Iran Aseman Airlines, Mahan Air, Kish Air, and Qeshm Air. These companies provide domestic and international flights and charter and cargo services. However, they face many challenges due to the international sanctions which limits their access to new aircraft, spare parts, and foreign markets.

There are 9 international, and 25 domestic airports in Iran.
