List of sovereign states and dependent territories in Oceania

Exclusive economic zones of the islands of Oceania and neighboring areas

This is a list of sovereign states and dependent territories in the geopolitical region of Oceania. Although it is mostly ocean and spans many continental plates, Oceania is occasionally listed as one of the continents.

This list follows the boundaries of geopolitical Oceania, which includes Australasia, Melanesia, Micronesia, and Polynesia. The main continental landmass of Oceania is Australia.^[1]

The boundary between Asia and Oceania is not clearly defined. For political reasons, the United Nations considers the boundary between the two regions to be the Indonesian–Papua New Guinean border.^[2] Papua New Guinea is occasionally considered Asian as it neighbours Indonesia, but this is rare, and it is generally accepted to be part of Oceania. Geographically, Papua and West Papua provinces are parts of Oceania.

Non-United Nations member states[]

Two states, the Cook Islands and Niue, are in free association with New Zealand. While maintaining a close constitutional and political relationship with New Zealand, both states are members of several United Nations specialized agencies with full treaty-making capacity, and have independently engaged in diplomatic relations with sovereign states under their own name. Both are also full members of the Pacific Islands Forum. Because of these features, they are sometimes considered to have de facto status as sovereign states.^[12]

Non-sovereign territories[]

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.
