The Pacific islands are a group of islands in the Pacific Ocean. They are further categorized into three major island groups: Melanesia, Micronesia, and Polynesia. Depending on the context, the term Pacific Islands may refer to one of several concepts: (1) those Pacific islands whose people have Austronesian origins, (2) the Pacific islands once or currently colonized after 1500 CE, (3) the geographical region of Oceania, or (4) any island located in the Pacific Ocean. This list of islands in the Pacific Ocean is organized by archipelago or political boundary.
