Sepilok Orang Utan Rehabilitation Centre is located about 25 kilometers west of Sandakan in the state of Sabah, East Malaysia. The centre opened in 1964 as the first official orangutan rehabilitation project for rescued orphaned baby orangutans from logging sites, plantations, illegal hunting or kept as pets. The orphaned orangutans are trained to survive again in the wild and are released as soon as they are ready.
The sanctuary is located within the Kabili-Sepilok Forest Reserve which covers an area of 4,294 ha (10,610 acres), much of which is virgin rainforest. Today around 60 to 80 orangutans are living free in the reserve. It has become one of Sabah's tourist attractions.
