Vanuu (from Sowa van uu "under the noise"), also known as Waterfall Village, is a large settlement on the southwestern coast of Pentecost Island in Vanuatu. The village consists of several scattered groups of houses within an aging coconut plantation.
Vanuu is located about 9 kilometres (5.6 mi) north of Lonorore Airport and about 8 kilometres (5.0 mi) south of Melsisi.
The large waterfall and associated natural swimming pool behind the village, and the presence of good anchorage for yachts, make Vanuu a popular destination for visitors to Pentecost Island. The waterfall behind Vanuu is one of seven major falls along the river; the others are located high in the bush. There is also a limestone cave nearby. Although Vanuu is not located within the area in which land diving is practised, it is sometimes used as a base by tourists who visit Pentecost to witness the ceremony.
Vanuu has a Churches of Christ church, a nakamal, small stores, and a guesthouse. Children from Vanuu attend the Anglophone primary school at Ranmawot, 2 km away. Ranwadi High School is also nearby.
Most villagers maintain gardens in the mountains above Vanuu, growing vegetables such as taro for local consumption and earning income from cash crops such as kava. Fees paid by visitors to the waterfall, and earnings from other tourist-related activities, are also a source of income.
