Tamuning, also known as Tamuning-Tumon-Harmon (Chamorro: Tamuneng) is a Municipality/ Town/ City or village located on the western shore of the United States territory of Guam. The village of Tamuning can be viewed as the economic center of Guam, containing Tumon (the center of Guam's tourist industry), Harmon Industrial Park, and commercial districts in other parts of the municipality. Its central location along Marine Corps Drive (the island's main thoroughfare) has aided in its development.
Tamuning is the site of the access roads and the old passenger terminal of Antonio B. Won Pat International Airport, the passenger airport for Guam. Fort Juan Muña, in Harmon, is a facility for the Guam Army National Guard.
The present and former locations of Guam Memorial Hospital, Guam's only civilian and government operated hospital, are in Tamuning. With Guam's only private birthing center also in the village, most modern civilian births on Guam take place in Tamuning.
