Orangutan Foundation identifies International Orangutan Day on August 19 and uses the date for orangutan conservation awareness

Annual dateReviewed 2026-09-07

About International Orangutan Day

International Orangutan Day is observed on August 19 as a global conservation-awareness day focused on orangutans and the protection of their habitats.

The observance is promoted by multiple conservation organizations rather than by a government or intergovernmental body.

Why International Orangutan Day matters

The day is intended to turn public attention toward orangutan conservation, habitat protection, rescue and rehabilitation work.

Because wildlife population estimates and threat assessments can change, factual conservation claims should be taken from current scientific or specialist conservation sources rather than repeated from undated observance copy.

History of International Orangutan Day

Orang Utan Republik Foundation says it co-created World Orangutan Events with partners to support International Orangutan Day and Orangutan Caring Week during 2014–2019.

Orangutan Conservancy documented an August 19 campaign involving more than 30 organizations in 2016, showing the observance’s multi-organization conservation character.

Orangutan Outreach currently maintains a dedicated August 19 campaign page, but available conservation histories do not establish one definitive original creator, inaugural edition or reason the date was selected.
