Samoan nationality refers to the Polynesian ethnic group originating from the Samoan Islands (Savai'i, Upolu, Manono, Apolima + smaller islets) in the central South Pacific.
Samoans are **Polynesian**—linguistically (Samoan language, Austronesian), genetically (mixed Asian/Papuan ancestry ~3,000 BP), culturally (fa'a Samoa). Closest relatives: Tongans, Tokelauans, Tuvaluans, Niueans, Cook Islanders, Māori, Hawaiians.
Whether in Apia, Auckland, Salt Lake City, or San Francisco, Samoan identity centers on aiga (family), matai (chiefly system), lotu (church), and tautua (service). Nationality is lived through these obligations, not just passport color.
