Polynesian outliers are a number of culturally Polynesian societies that geographically lie outside the main region of Polynesian influence, known as the Polynesian Triangle. Instead, Polynesian outliers are scattered in the two other Pacific subregions, Melanesia and Micronesia. Based on archaeological and linguistic analysis, these islands are considered to have been colonized by seafaring Polynesians, mostly from the area of Samoa, Tonga, and Tuvalu.
