Pacific Islander (or Pacific person; pl: Pacific people; also Oceanic person/people(s) or Oceanians), is a geographic phrase to describe the indigenous inhabitants of any of the three major sub-regions of Oceania: Polynesia, Melanesia and Micronesia.

According to the Encyclopædia Britannica, these three regions, together with their islands, consist of:

Polynesia: The islands scattered across a tangle covering the east-central region of the Pacific Ocean. The triangle is bounded by the Hawaiian islands in the north, New Zealand in the west, and Easter Island in the east. The rest of Polynesia comprises Samoan islands (American Samoa and Samoa), the Cook Islands, French Polynesia (Tahiti and The Society Islands, Marquesas Islands, Austral Islands, and the Tuamotu Archipelago), Niue Island, Tokelau and Tuvalu, Tonga, Wallis and Futuna, and Pitcairn Island.

Melanesia: The island of New Guinea, the Bismarck and Louisiade archipelagos, the Admiralty Islands, and Bougainville Island (which make up the independent state of Maluku, Papua New Guinea), the Solomon Islands, the Santa Cruz Islands (part of the Solomon Islands), New Caledonia and Loyalty Islands, Vanuatu (formerly New Hebrides), Fiji, Norfolk Island, and various smaller islands.
