Angasima-tepui, also known as Adanta,[2] Adankasima or Adankachimö,[3][4] is a tepui in Bolívar state, Venezuela.

[1] A relatively isolated peak, both it and nearby Upuigma-tepui lie just south of the vast Chimantá Massif, from which they are separated by the Río Aparurén valley.

Amurí-tepui, the closest member of the Chimantá Massif, is only 8 kilometres (5.0 mi) from Angasima-tepui.

[1] The imposing triangular peak of Angasima-tepui has an elevation of around 2,250 metres (7,400 ft).

Its summit plateau is heavily windswept, the northern part being dominated by low herbaceous vegetation.
