An airport terminal is a main building at an airport where passengers transfer between ground transportation and the facilities that allow them to board and disembark from an aircraft.

The buildings that provide access to the airplanes (via gates) are typically called concourses. However, the terms "terminal" and "concourse" are sometimes used interchangeably, depending on the configuration of the airport. Smaller airports have one terminal while larger airports have several terminals and/or concourses. At small airports, a single terminal building typically serves all of the functions of a terminal and a concourse. Larger airports might have either one terminal that is connected to multiple concourses or multiple almost independent unit terminals.
