The following are entities considered to be within Oceania which are either:
1. Federal territories of sovereign states located outside these states' mainland.
2. Territories that constitute integral parts of sovereign states in some form other than a federal relationship, where a significant part of the sovereign state's landmass is located outside Oceania or the territory is located outside the sovereign state's mainland. Many of these territories are often described as dependencies or autonomous areas.
3. Dependent territories of sovereign states.
Two of these territories (French Polynesia and New Caledonia) are associate members of the Pacific Islands Forum, while five others (American Samoa, Guam, Northern Mariana Islands, Tokelau, and Wallis and Futuna) hold observer status within the organization.
