Angasima-tepui, also known as Adanta, Adankasima or Adankachimö, is a tepui in Bolívar state, Venezuela. 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 valley. Amurí-tepui, the closest member of the Chimantá Massif, is only 8 kilometres (5.0 mi) from Angasima-tepui. The undescribed pitcher plant Heliamphora sp. 'Angasima Tepui' is endemic to the summit region of Angasima-tepui.
