Mariehamn Airport (Swedish: Mariehamns flygplats, Finnish: Maarianhaminan lentoasema, (IATA: MHQ, ICAO: EFMA) is located in Jomala, Åland (a territory of Finland). The airport is located some 3 kilometres (2 mi) north-west of Mariehamn town centre. It served 61,568 passengers in 2017 and is operated by the state-owned Finavia.

The airport has a duty-free shop where passengers may purchase goods such as alcohol without paying VAT and other taxes, when flying to destinations outside Åland, including to Finland. Normally local taxes must be paid in airport shops before travelling inside the EU, but Åland is outside the EU VAT area, to allow tax-free sales onboard ferries and at the airport. Åland is in other respects a part of the EU.

The Aero Flight 217 aviation accident that resulted in 22 deaths occurred near the airport in 1963.
