Aunuʻu is a small volcanic island off the southeastern shore of Tutuila in Saʻole County, American Samoa. It has a land area of 374.83 acres (0.59 sq mi; 1.52 km), and a 2010 census population of 436 persons. Politically, it is a part of the Eastern District, one of the two primary political divisions of American Samoa.
The island of Aunu’u is home to three villages: Le’auuliuli, Saluavatia, and Alofasau. Politically, the island is divided into two sections, Saole and Saleaaumua. The entirety of Saluavatia and half of Le’auuliuli are part of Saole, while the remaining half of Le’auuliuli, along with Alofasau, constitute Saleaaumua. The names of the villages are derived from the Samoan language. Le’auuliuli translates to "the black stalk," whereas Saluavatia means "a second Vatia."
