Park Township Airport (IATA: HLM, ICAO: KHLM, FAA LID: HLM) was a public airport located in Park Township, 3 mi (5 km) northwest of Holland, Michigan, United States. Built in 1937, the airport was operated by Ottawa Aviation, an organization of local users whose aim was to promote the value of the airport to the surrounding community. The airport had a main paved runway (5/23) that was demolished around August 15, 2020, and an intersecting grass runway (12/30) that still exists today. With the failure of a millage, the airport no longer supports fixed wing aircraft.
