Heathrow Terminal 2, also known as The Queen's Terminal, is an airport terminal at Heathrow Airport, the main airport serving London, United Kingdom. The new development was originally named Heathrow East Terminal, and occupies the sites where the previous Terminal 2 and the Queens Building stood. It was designed by Luis Vidal + Architects and opened on 4 June 2014. The original Terminal 2 opened in 1955 as the Europa Building and was the airport's oldest terminal.

The Queens Building was an office building at London Heathrow Airport next to Heathrow Terminal 2. It was opened in 1955 by Queen Elizabeth II and was demolished in 2009 to make room for a rebuilt Terminal 2. It was the location of the operational offices of BAA until demolition.
