The Manuʻa Islands, or the Manuʻa tele, in the Samoan Islands, consists of three main islands: Taʻū, Ofu and Olosega. The latter two are separated only by the shallow, 137-meter-wide Āsaga Strait, and are now connected by a bridge over the strait. The islands are located some 110 kilometers east of Tutuila and are a part of American Samoa, an unincorporated territory of the United States. Their combined area is 56 square kilometers, and they have a total population of 1,400. Taʻu is the largest of these islands, with an area of 44 km2 (17 sq mi), and it has the highest point of the Manuʻa, at 931 meters. Politically, the islands form the Manuʻa District, one of the three administrative divisions of American Samoa.

Taʻū is the largest inhabited island in the Manuʻa Islands and the easternmost volcanic island of the Samoan Islands. Taʻū is part of American Samoa. In the early 19th century, the island was sometimes called Opoun.
