Orangutan Foundation International (OFI) is a nonprofit organization dedicated to the conservation of wild orangutans and their rainforest habitat. OFI also supports research on orangutans and forests, education initiatives, both local and international, and brings awareness concerning orangutans wherever it can.

OFI is profoundly committed to the welfare of all orangutans, whether captive, ex-captive, or wild. Established by Dr. Biruté Mary Galdikas and associates in 1986, OFI operates Camp Leakey, an orangutan research center, within Tanjung Puting National Park.
