King Fahd International Airport (Arabic: مطار الملك فهد الدولي; abbr. KFIA) (IATA: DMM, ICAO: OEDF), also known as Dammam International Airport or simply Dammam Airport or King Fahd Airport, is the international airport serving Dammam, Saudi Arabia. The airport is located 31 kilometres (19 miles) northwest of downtown Dammam and is named after the former King of Saudi Arabia, Fahd ibn Abdulaziz (1921–2005). The airport serves the entire Eastern Province of Saudi Arabia and is one of the four primary international airports in the kingdom.

Formerly a US airbase used primarily during the Gulf War, the airport has been overseeing commercial operations since 28 November 1999 and has since expanded to provide connections to 43 destinations. Before King Fahd International, the primary airport serving the region was the much busier Dhahran International Airport, which has since been converted for military use and is now designated the King Abdulaziz Air Base. Since 1 July 2017, the airport has been operated and managed by the Dammam Airports Company (DACO). Commercial transport was only halted once throughout the history of the airport when, on 21 March 2020, the Saudi Press Agency (SPA) announced the suspension of all domestic and international travel both within and to and from the kingdom due to the COVID-19 pandemic. Domestic operations were reinitiated on 31 May 2020, and international operations resumed on 17 May 2021.

The third largest airport in the kingdom by passenger volume, more than 10 million passengers use King Fahd International each year, and 37 airlines operate flights in and out of the airport. The airport serves as a hub to Flynas and Flyadeal.
