Ātua is an ancient political district of Samoa, consisting of most of the eastern section of Upolu and the island Tutuila. Within Samoa's traditional polity, Ātua is ruled by the Tui Ātua together with the group of six senior orators of Lufilufi and 13 senior matai from throughout Ātua, comprising the Fale Ātua (or parliament of Atua). The fono (meeting) of Atua's rulers takes place in Lufilufi on the great malae of Lalogafu'afu'a.
The paramount pāpā title and sovereign of Ātua is the Tui Ātua. The title traces its lineage to Pili, son of Tagaloa-a-lagi. The first Tui Atua was Lufasiaitu who lived around 700AD. It is from his lifetime that the known pre-European history of Samoa associated with the Tui Ātua and its holders began. The current Tui Ātua is former Prime Minister, Head of State and tama-a-aiga, Tui Atua Tupua Tamasese Efi. The Tui Atua title is the oldest active title in Polynesia.
