Cagayan de Sulu Airport is an airport serving the general area of Mapun Island (formerly Cagayan de Sulu), in the province of Tawi-Tawi.

Cagayan de Sulu Airport is located in Barangay Mapun, approximately 6 km (3.7 miles) from Mapun town center. It takes about 16 minutes to reach the airport from the town center under normal traffic conditions.

The airport is classified as a community or feeder airport primarily used for military operations, with no current commercial airline service.

The airport has a single runway oriented 13/31, with a length of 1,300 meters (4,265 feet), surfaced with macadam.

Planned expansions could extend the runway up to 2 kilometers, allowing it to support small passenger and cargo planes and serve as a reliever for Zamboanga International Airport.

Cagayan de Sulu Airport has minimal facilities reflecting its community airport status:

• Basic terminal, serving primarily military use; no airlines currently operate.
• No restaurants, lounges, ATMs, or WiFi.
• No vehicle parking; taxis, buses, and ride-sharing services available at the airport.
