Hong Kong International Airport is Hong Kong's main airport, built on reclaimed land on the island of Chek Lap Kok, Hong Kong. The airport is also referred to as Chek Lap Kok International Airport or Chek Lap Kok Airport, to distinguish it from its predecessor, the former Kai Tak International Airport.

Hong Kong International Airport covers an area of 1,255 hectares. The airport has a total of 90 boarding gates, with 77 jet bridge gates and 12 virtual gates which are used as assembly points for passengers, who are then ferried to the aircraft by apron buses. Of the 66 jet bridges, five are capable of handling the Airbus A380, the current users of which are Asiana Airlines, British Airways, Emirates, Qantas, and Singapore Airlines.

In November 2022, the Sky Bridge opened as part of a wider HK$9 billion airport upgrade, connecting Terminal 1 to the North Satellite Concourse (NSC). Lined with glass floor panels at the edges, the 200-meter-long, 28-meter-high bridge, the largest of its kind, is high enough for an Airbus A380 to pass underneath.

With the exterior glazing and glass floor installed on the bridge, the airport notes that “passengers can enjoy the extraordinary experience of an aircraft passing beneath their feet”. With the unique panoramic view across the airport, Sky Bridge offers the highest view point of the airport for passengers. An observation deck, a catering outlet and a shop on the Sky Bridge will open in phases.

Having been in commercial operation since 1998, Hong Kong International Airport is one of the largest trans-shipment centers, passenger hubs, and gateways for destinations in inland China, Asia, and the world. The airport is the world's busiest cargo gateway and one of the world's busiest passenger airports. It is also home to one of the world's largest passenger terminal buildings (the largest when opened in 1998).

HKIA is an important contributor to Hong Kong's economy, with approximately 65,000 employees. More than 100 airlines operate flights from the airport to over 180 cities across the globe. In 2015, HKIA handled 68.5 million passengers, making it the 8th busiest airport worldwide by passenger traffic and the 4th busiest airport worldwide by international passenger traffic.
