Jaffna International Airport (Tamil: யாழ்ப்பாணம் சர்வதேச விமான நிலையம், romanized: Yāḻppāṇam Carvatēca Vimāṉa Nilaiyam; Sinhala: යාපනය ජාත්‍යන්තර ගුවන්තොටුපළ, romanized: Yāpanaya Jātyantara Guvantoṭupaḷa) (IATA: JAF, ICAO: VCCJ), formerly known as Palaly Airport and Jaffna Airport, is an international airport serving northern Sri Lanka. It was also a military airbase known as Sri Lanka Air Force Palaly or SLAF Palaly. The airport is located in the town of Palaly near Kankesanthurai, 7 nautical miles (13 km; 8 mi) north of the city of Jaffna. It is at an elevation of 10 m (34 ft) and has one runway designated 05/23 with an asphalt surface measuring 1,400 by 30 metres (4,593 ft × 98 ft).

The airport was originally built by the Royal Air Force during World War II, after which it functioned as the country's second international airport. It was taken over by the Sri Lanka Air Force during the Sri Lankan Civil War. Domestic civilian flights resumed in the mid-1990s and in 2019 it became Sri Lanka's third international airport. The inauguration of the Jaffna International Airport marked a significant milestone. Subsequently, scheduled flights connecting Jaffna and Chennai commenced in November of the same year. These ventures and cooperative efforts work in tandem to reinforce the well-established people-to-people connections that exist between India and Sri Lanka.
