Antonio B. Won Pat International Airport, also known as Guam International Airport, is an airport located in Tamuning and Barrigada, three miles (4.8 km) east of the capital city of Hagåtña in the United States territory of Guam. The airport is a hub for Asia Pacific Airlines and for United Airlines, serving as the latter's Pacific Ocean hub. It is also the home of the former Naval Air Station Agana, and is the only international airport in the territory. The airport is named after Antonio Borja Won Pat, the first delegate from Guam to the United States House of Representatives, and is operated by the A.B. Won Pat International Airport Authority, Guam, an agency of the Government of Guam.

Hagåtña is the capital village of the United States territory of Guam. From the 18th through mid-20th century, it was Guam's population center, but today it is the second smallest of the island's 19 villages in both area and population. However, it remains one of the island's major commercial districts in addition to being the seat of government.
