Wei-Assipu-tepui, also known as Little Roraima or Roraimita, is a minor tepui of the Eastern Tepuis chain. It lies just off the northeastern flank of Roraima-tepui, directly on the border between Brazil and the disputed Guayana Esequiba territory, claimed by Venezuela but controlled by Guyana, and very close to the tripoint of all three countries. The mountain is known for its extensive cave systems, with one extending for over a kilometre.

Wei-Assipu-tepui has a maximum elevation of around 2,400 metres (7,870 ft). Its summit plateau is highly dissected and generally inclined south-southwest (towards the Brazilian side). The rocky summit is partially forested, with flowering plants of the genus Bonnetia featuring prominently. It also hosts a number of carnivorous plants, including Heliamphora glabra, Heliamphora nutans, and the natural hybrid between the two. The various rock cavities of Wei-Assipu-tepui are home to nesting colonies of white-collared swifts (Streptoprocne zonaris) and oilbirds (Steatornis caripensis). For the latter species, Wei-Assipu-tepui is the easternmost recorded locality in mainland South America, and the first known nesting site in Brazil. The mountain's summit supports a greater variety of herpetofauna than the less vegetated plateaus of nearby Roraima-tepui, Kukenán-tepui, Yuruaní-tepui, and Ilú-tepui. Day temperatures of 17 °C have been recorded on the summit plateau, falling to 12 °C overnight, with slightly lower values in the more sheltered caves.
