The following is an alphabetical list of subregions in the United Nations geoscheme for Oceania, created by the United Nations Statistics Division (UNSD).[1]

UN Subregions

Oceania with its sovereign and dependent islands within the subregions Melanesia, Micronesia, Polynesia and Australasia

The United Nations geoscheme subdivides the region into Australia and New Zealand, Melanesia, Micronesia, and Polynesia. The UNSD notes that "the assignment of countries or areas to specific groupings is for statistical convenience and does not imply any assumption regarding political or other affiliation of countries or territories".[1] The number between parentheses is the UN M49 code (009 for the whole of Oceania).
