Guam (/ˈɡwɑːm/; Chamorro: Guåhan [ˈɡʷɑhɑn]) is an organized, unincorporated territory of the United States in Micronesia subregion of the western Pacific Ocean. It is the westernmost point and territory of the United States; in Oceania, it is the largest and southernmost of the Mariana Islands and the largest island in Micronesia. Guam’s capital is Hagåtña, and the most populous city is Dededo.
Hagåtña (/həˈɡɑːtnjə/; Chamorro pronunciation: [hæˈɡɑtɲæ]; formerly in English: Agana /əˈɡɑːnjə/, in Spanish: Agaña) 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.
