NAIA Terminal 4, also known as the Old Domestic Terminal, holds the distinction of being the oldest terminal still in operation at Ninoy Aquino International Airport. This terminal exclusively handles domestic turbo-prop flights.

Terminal 4 is unique as it is the only terminal at NAIA without jet bridges. In the past, it accommodated Airbus A320 operations, but these were moved to Terminal 2 in 2023 to streamline airport functions.

In September 2024, a consortium led by the San Miguel Group will assume control of NAIA's operations. Among their plans is the closure of Terminal 4, although an official date for the closure has not yet been announced.
