Bornean Orangutans are a species of orangutan, great apes native to the rainforests of Malaysia and Indonesia. Prior to 2017 there were two recognised species of orangutan, the Bornean and the Sumatran, but in November 2017 a third species found only in the north of Sumatra was described, the Tapanuli Orangutan.

How or when this skull came into the Museum's collections or exactly where in Borneo it was from is not known but its original registration number suggests it was acquired early in the Museum's history. It was identified as being from a Bornean Orangutan in 1988.

Populations of Bornean Orangutans are declining rapidly due to the destruction and fragmentation of their habitat and hunting. Their long life-spans and slow reproduction means that populations are slow to recover from negative impacts and over the last decade populations in Borneo have fallen by 25% to below 100,000 individuals.

Because of the their small populations and the threats to their habitat Bornean Orangutans are classified by the International Union for Conservation of Nature (IUCN) as Critically Endangered. They are listed on Appendix I of the Convention on International Trade in Endangered Species (CITES) which bans trade in them or their products to ensure that international trade does not threaten them with extinction.
