The Dani are an ethnic group from the Central Highlands of Western New Guinea in Baliem Valley, Highland Papua, Indonesia. Around 100,000 people live in the Baliem Valley, consisting of representatives of the Dani tribes in the lower and upper parts of the valley each 20,000 and 50,000 in the middle part. The areas west of the Baliem Valley are inhabited by approx 180,000, representatives of the Lani people, incorrectly called "Western Dani". All inhabitants of Baliem Valley and the surrounding areas are often called Dani hence they are also sometimes conflated with other highland tribes such as Lani in the west; Walak in the north; Nduga, Mek, and Yali in the south and east.
