London City Airport (IATA: LCY, ICAO: EGLC) is an international airport in London, England, United Kingdom. It is located in the Royal Docks in the Borough of Newham, approximately 6 miles (9.7 km) east of the City of London and 3 miles (4.8 km) east of Canary Wharf. These are the twin centres of London's financial industry, which is a major user of the airport. The airport was developed by the engineering company Mowlem in 1986–87. In 2016 it was bought by a Canadian-led consortium of Alberta Investment Management Corporation (AIMCo), OMERS, the Ontario Teachers' Pension Plan and Wren House Infrastructure Management of the Kuwait Investment Authority.

London City Airport has a single 1,508-metre-long (4,948 ft) runway, and a CAA Public Use Aerodrome Licence (Number P728) that allows flights for the public transport of passengers; this licence also allows training flights, but only for the purpose of training pilots to operate at this specific airport. Only multi-engine, fixed-wing aircraft up to Airbus A318 size with special aircraft and aircrew certification to fly 5.5° approaches are allowed to conduct operations at London City Airport. As of 2020, the airport is about 60 hectares (150 acres) in size.

London City had over 4.5 million passenger movements in 2017. It is the fifth-busiest airport by passengers and aircraft movements serving the London area — after Heathrow, Gatwick, Stansted and Luton — and was the 14th-busiest in the UK in 2017.
