Gatwick Airport (IATA: LGW, ICAO: EGKK) is located 3.1 mi (5.0 km) north of the centre of Crawley, West Sussex, and 29.5 mi (47.5 km) south of Central London. Previously known as London Gatwick, it is London's second largest international airport and second busiest by total passenger traffic in the United Kingdom after Heathrow.

In 2012, 34.2 million passengers passed through Gatwick.

Gatwick Airport has two terminals, called North and South. The terminals are connected by a transit system consisting of three-car automatic driverless vehicles that run along a 1.2km long elevated two-way track. The transit is free to use with a travel time of one minute fifty-six seconds. It runs every three minutes in peak travel periods (when two vehicles are used), and every six minutes at all other times (when one vehicle shuttles back and forth).

The name "Gatwick" dates back to 1241, and was the name of a manor on the site of today's airport until the 19th century. It is derived from the Anglo-Saxon words gat, 'goat', and wic, 'dairy farm', i.e. 'goat farm'.
