Tui Ātua Tupua Tamasese Tupuola Tufuga Efi (born Olaf "Efi" Tamasese; 1 March 1938) is a Samoan paramount chief, politician and statesman who served as prime minister of Samoa from 1976 to 1982 and again later in 1982, and as O le Ao o le Malo (head of state) of Samoa from 2007 to 2017. He is currently a member of the Council of Deputies, having previously sat on the council from 2004 to 2007.

As a paramount chief, he heads one of Samoa's two royal families, the Sā Tupua (descendants of Queen Salamasina), through the family's maximal lineage title, Tupua Tamasese; he also holds the ancient pāpā title of Tui Ātua (sovereign of Atua).
