Imam Khomeini International Airport (IATA: IKA; ICAO: OIIE) is the primary international airport of Tehran, the capital city of Iran, located south of Tehran. All international flights in Tehran are currently served by this airport, and all domestic flights are served by Mehrabad Airport. IKA ranks third in terms of total passenger traffic in Iran after Tehran Mehrabad Airport and Mashhad Airport. The airport is operated by the Iran Airports Company and is the primary operating base for Iran Air and Mahan Air.

The original opening was scheduled for 11 February 2004, the onset of the auspicious "Ten-Day Dawn" (1–11 February) celebrations, marking the anniversary of the 1979 Islamic Revolution. There were numerous issues surrounding the construction of the airport including the supply of fuel to the new airport, and a delay in signing a deal with the Iranian oil ministry forced a delay in the opening of the airport until 8 May 2004. Just prior to the opening on 8 May, two local airlines refused to switch to the new airport.
