Helsinki-Malmi Airport (Finnish: Helsinki-Malmin lentoasema, Swedish: Helsingfors-Malm flygplats) (IATA: HEM, ICAO: EFHF) was an airfield that served Helsinki, the capital of Finland, located in the district of Malmi, 5.4 NM (10.0 km; 6.2 mi) north-north-east of the city centre. It was opened in 1936. Until the opening of Helsinki-Vantaa Airport in 1952, it was the main airport of Helsinki and of Finland. After that, it was used for general aviation and flight training, and remained the second-busiest airport in Finland, as measured by the number of landings, after Helsinki-Vantaa Airport. The city of Helsinki, which owns the land the airport is located on, terminated its lease agreement for aviation purposes in December 2019, and its remaining runway was closed in March 2021. After legal disputes, which were eventually resolved in favor of the city of Helsinki, the airport was removed from Fintraffic's eAIP manual in June 2025. The city plans to use the land for the construction of approximately 25,000 new apartments starting in 2024.
