Heathrow Terminal 5 is an airport terminal at Heathrow Airport, the main airport serving London. Opened in 2008, the main building in the complex is the largest free-standing structure in the United Kingdom. Until 2012 the terminal was used solely by British Airways. It was then exclusively used as one of the three global hubs of IAG, served by British Airways and Iberia until 12 July 2022, when Iberia moved all flights to Terminal 3, leaving British Airways as sole user again.

The terminal was designed to handle 72.29 million passengers a year. In 2018, Terminal 5 handled 32.1 million passengers on 211,000 flights. It was the busiest terminal at the airport, measured both by passenger numbers and flight movements.^[1]

The building's leading architects were from the Richard Rogers Partnership and production design was completed by aviation architects Pascall+Watson. The engineers for the structure were Arup and Mott MacDonald. The building cost £4 billion and took almost 20 years from conception to completion, including the longest public inquiry in British history.
