General Santos International Airport (; ; ; ), also known as Tambler Airport, is an alternate international airport located in the city of General Santos, Philippines serving the greater area of Soccsksargen. Situated in Fatima, General Santos, it is the largest airport on the island of Mindanao and is officially classified as an international airport by the Civil Aviation Authority of the Philippines (CAAP), a government bureau which is responsible for the management and operations of General Santos International Airport and all other airports in the country except regular international airports.
