Koobi Fora, Prehistoric fossil excavation site near Lake Turkana, Kenya.

Koobi Fora is an archaeological site in Kenya with sedimentary rock layers that preserve over 2 million years of Earth's history. The location holds fossil remains, stone tools, and geological records that show how early human species lived and adapted.

A research team led by Richard Leakey set up a base camp here in 1968 and began systematic excavations. Major discoveries followed, including the skull KNM-ER 1470, which transformed understanding of early human development.

The name Koobi Fora comes from the Gabbra language and, according to the National Museums of Kenya, means "a place of the commiphora and the source of myrrh". The Gabbra are nomadic herders who live near the ridge on the eastern shore of Lake Turkana. The name now covers the whole region of Sibiloi National Park, and the term East Turkana is also used for it.

Access is organized through guided tours managed by the National Museums of Kenya, which take visitors through designated excavation areas. The site is best visited during drier months when paths and roads are easier to navigate.

The first stone tools at Koobi Fora were found at a spot nicknamed the KBS site, after researcher Kay Behrensmeyer, who discovered them in Area 105. The same site gave its name to the KBS Tuff, the volcanic layer used to date the fossil-bearing sediments.
