Lučko Airfield (ICAO: LDZL, Croatian: Zračno pristanište Lučko) is an airfield for general aviation and unscheduled air transport, located in Ježdovec near Lučko, in central Croatia, 11 kilometres (6.8 mi) southwest of Zagreb. It is operated by Aeroklub Zagreb and has two parallel grass runways measuring 850 by 30 metres (2,789 ft × 98 ft). Due to the lack of surfacing on the runways, it is only used from spring to autumn in dry periods. Aside from traffic, the airport is today a venue for air shows, such as Zagreb Air Show and Adria Air Race and an operation base for civilian pilot training.

Lučko was formerly Zagreb's main international airport, and later supported military aviation. It was constructed in 1943 and saw commercial operations from 1947 to 1959, after which commercial traffic was moved to the new Zagreb Airport with paved runways in Pleso. Lučko thereafter remained an airport for military and general aviation. Today it is also used by Croatian special police's Lučko Anti-Terrorist Unit.

The airport is equipped to serve light aircraft, helicopters, gliders, ultralight aviation, UAVs and parachuting. It is connected to Zagreb and Lučko by a regular bus line.
