Oceania (UK: /ˌoʊʃiˈɑːniə, ˌoʊsi-/ or US: /ˌoʊʃiːˈæniə/) is a term used to denote a region, comprising Australia and neighboring islands. Oceania consists of four subregions: Australasia, Melanesia, Micronesia, and Polynesia. Located in the eastern and western hemispheres, Oceania covers an area of 8,525,989 square kilometres (3,291,903 sq mi) and has a population of 41,050,699. Oceania is the smallest continental grouping in land area and the second smallest after Antarctica in population.

The islands at the geographic extremes of Oceania are Bonin Islands, a politically integral part of Japan, Hawaii, a state of the United States, and Easter Island, belonging to Chile. Oceania has a diverse mix of economies from the highly developed and globally competitive financial market of Australia and New Zealand, which rank high in quality of life and human development index, to the much less developed economies that belong to countries such as of Kiribati and Tuvalu. The largest and most populous country in Oceania is Australia, with Sydney being the largest city of both Oceania and Australia.
