The Malua BioBank is a 34,000 hectare rainforest reserve in Sabah, Malaysia, on the island of Borneo.

Situated in the Heart of Borneo, the area is larger than the country of Malta and almost half the size of Singapore. Malua is home to one of the highest concentrations of orang-utans in the world. Clouded leopards, sun bears, rhinos, pygmy elephants and over 300 bird species also inhabit this protected area.

Sitting adjacent to the Danum Valley Conservation Area, one of the last pristine lowland tropical rainforests, the Malua BioBank provides crucial habitat between virgin lowland tropical rainforest and oil palm plantations.
