The Pacific Islands large aquatic ecosystem comprises the U.S. territories of Guam, the Commonwealth of the Northern Mariana Islands (CNMI), and American Samoa.

The watershed of the Pacific Islands large aquatic ecosystem covers an area of 470 square miles. The economy of the three territories is driven by tourism, the U.S. military, and fishing.
