Tallinn Airport (Estonian: Tallinna lennujaam, IATA: TLL, ICAO: EETN) or Lennart Meri Tallinn Airport (Estonian: Lennart Meri Tallinna lennujaam) is the largest airport in Estonia, which serves as the secondary hub for AirBaltic and the cargo airline Airest. It was also the home base of the now defunct national airline Estonian Air. Tallinn Airport is open to both domestic and international flights. It is located 2.7 nautical miles (5.0 km; 3.1 mi) southeast of the centre of Tallinn on the eastern shore of Lake Ülemiste. It was formerly known as Ülemiste Airport.

The airport has a single asphalt/concrete runway, 08/26, that is 3,480 m × 45 m (11,417 ft × 148 ft) and large enough to handle wide-bodied aircraft such as the Boeing 747, six taxiways and seventeen terminal gates. Since 2009, the airport is officially known as Lennart Meri Tallinn Airport, named after former president of Estonia Lennart Meri.
