American Samoa (/əˈmɛrɨkən səˈmoʊ.ə/ ( listen); Samoan: Amerika Sāmoa, IPA: [aˈmɛɾika ˌsaːˈmoa]; also Amelika Sāmoa or Sāmoa Amelika) is an unincorporated territory of the United States located in the South Pacific Ocean, southeast of the Independent State of Samoa (formerly known as Western Samoa). The main (largest and most populous) island is Tutuila, with the Manuʻa Islands, Rose Atoll, and Swains Island also included in the territory.

American Samoa is part of the Samoan Islands chain, located west of the Cook Islands, north of Tonga, and some 300 miles (500 km) south of Tokelau. To the west are the islands of the Wallis and Futuna group.

The 2010 census showed a total population of 55,519 people. The total land area is 76.1 square miles (197.1 km²), slightly more than Washington, D.C. American Samoa is the southernmost territory of the United States.

Contact with Europeans began in the early 18th century. Jacob Roggeveen (1659–1729), a Dutchman, was the first known European to sight the Samoan islands in 1722. This visit was followed by the French explorer Louis-Antoine de Bougainville (1729–1811), who named them the Navigator Islands in 1768. Contact was limited before the 1830s which is when English missionaries and traders began arriving.

Samoa (ⁱ/səˈmoʊ.ə/; Samoan: Sāmoa, IPA: [ˌsaːˈmoa]), officially the Independent State of Samoa (Samoan: Malo Sa'oloto Tuto'atasi o Sāmoa), formerly known as Western Samoa, is a country encompassing the western part of the Samoan Islands in the South Pacific Ocean. It became independent from New Zealand in 1962. The two main islands of Samoa are Upolu and one of the biggest islands in Polynesia, Savai'i. The capital city, Apia, and Faleolo International Airport are situated on the island of Upolu.

Samoa was admitted to the United Nations on 15 December 1976. The entire island group, inclusive of American Samoa, was called Navigators Islands by European explorers before the 20th century because of the Samoans' seafaring skills.

The oldest date so far from pre-historic remains in Samoa has been calculated by New Zealand scientists to a likely true age of circa 3,000 years ago from a Lapita site at Mulifanua during the 1970s.

The origins of the Samoans is closely linked to modern research about Polynesia in various scientific disciplines such as genetics, linguistics and anthropology. Scientific research is ongoing although a number of different theories exist; including one proposing that the Samoans originated from Austronesian predecessors during the terminal eastward Lapita expansion period from Southeast Asia and Melanesia between 2,500 and 1,500 BCE. The Samoan origins are currently being reassessed due to new scientific evidence and carbon dating findings from 2003 and onwards.
