Lumbia Airfield (IATA: CGY, ICAO: RPML), formerly known as Lumbia Airport and Cagayan de Oro Airport, is an air base and was the main civilian airport that served the general areas of Cagayan de Oro and Northern Mindanao, in the province of Misamis Oriental in the Philippines. It was the second busiest airport in Mindanao, after Francisco Bangoy International Airport in Davao City before the opening of Laguindingan Airport.

It was classified as a Class 1 principal (major domestic) airport by the Civil Aviation Authority of the Philippines, a body of the Department of Transportation that is responsible for the operations airports in the Philippines (except major international ones).

Lumbia Airfield took its name from its location in Barangay Lumbia. It now serves as a minor air base of the Philippine Air Force, with service equipment of OV-10 Bronco aircraft as well as UH-1 Huey and MD-520MG Defender helicopters.

On June 15, 2013, Laguindingan Airport in the municipality of Laguindingan, Misamis Oriental, some 46 kilometers (29 mi) northwest of the city, replaced Lumbia Airport. The new airport serves Northern Mindanao, as well as its major cities, Iligan and Cagayan de Oro.
