Reykjavík Airport (Icelandic: Reykjavíkurflugvöllur) (IATA: RKV, ICAO: BIRK) is the main domestic airport serving Reykjavík, the capital of Iceland, located about two kilometres (1+1⁄4 miles) from the city centre. It is the domestic hub of Icelandair and Eagle Air flights and has two runways. Reykjavík Airport is owned and operated by the state enterprise Isavia.

Having shorter runways than the larger Keflavík International Airport, which is sited 50 kilometres (30 mi) out of town, it serves only domestic flights within Iceland and limited Greenland flights. The airport also services medivac, private aviation and general aviation.

It can also serve as alternate airport for flights inbound towards Keflavík, in case of adverse weather conditions there. To distinguish from the larger Keflavík International Airport outside Reykjavík, it is sometimes unofficially in English called Reykjavik City Airport (also by the airport administration), and also Reykjavik Domestic Airport.
