Osun-Osogbo is a sacred grove along the banks of the Osun river just outside the city of Osogbo, Osun State of Nigeria.

The Osun-Osogbo Grove is several centuries old and is among the last of the sacred forests that once adjoined the edges of most Yoruba cities before extensive urbanization. In recognition of its global significance and cultural value, the Sacred Grove was inscribed as a UNESCO World Heritage Site in 2005.
