Berlin Brandenburg Airport Willy Brandt (German: Flughafen Berlin Brandenburg „Willy Brandt“, (IATA: BER, ICAO: EDDB), German pronunciation: [beːʔeːˈʔɛɐ̯] ) is an international airport in Schönefeld, just south of the German capital and state of Berlin, in the state of Brandenburg. Named after the former West Berlin mayor and West German chancellor Willy Brandt, it is located 18 kilometres (11 mi) south-east of the city centre and serves as a base for Eurowings, easyJet and Ryanair. It mostly has flights to European metropolitan and leisure destinations as well as a number of intercontinental services.

The new airport replaced Tempelhof, Schönefeld, and Tegel airports, and became the single commercial airport serving Berlin and the surrounding State of Brandenburg, an area with 6 million inhabitants. With projected annual passenger numbers of around 34 million, Berlin Brandenburg Airport has become the third busiest airport in Germany, surpassing Düsseldorf Airport and making it one of the fifteen busiest in Europe.

At the time of opening, the airport had a theoretical capacity of 46 million passengers per year. Terminal 1 accounts for 28 million of this; Terminal 2, which did not open until 24 March 2022, having been delayed by the COVID-19 pandemic, accounts for 6 million; and Terminal 5, the terminal buildings of the former Berlin-Schönefeld Airport, accounts for another 12 million. Planned further expansion would bring the airport's total annual capacity to 58 million passengers by 2035.

The airport was originally planned to open in October 2011, five years after starting construction in 2006. The project encountered a series of successive delays due to poor construction planning, execution, management, and corruption.
