Homo naledi är en art i släktet Homo som levde under pleistocen. Arten upptäcktes 2013 av två speleologer i grottkomplexet Rising star cave, som ingår i det sydafrikanska världsarvet Cradle of humankind i Gauteng-provinsen. Speleologerna Rick Hunter och Steven Tucker upptäckte resterna av åtminstone femton individer, vilket är det största enskilda fynd av en människoliknande art som någonsin gjorts i Afrika.[1]
Definitionen av arten utarbetades i samband med utgrävningar 2015 av bland andra den amerikanske paleontologen och arkeologen Lee Rogers Berger.[1][2]
Etymologi
Ordet naledi betyder "stjärna" på sesotho- och setswana-språken, två av de elva nationalspråken i Sydafrika. Artnamnet kan därför sägas betyda ”stjärnmänniskan”. Det anspelar på fyndplatsen, grottsystemet vid Rising star cave.[1]

Cartoon illustrating the geological and taphonomic context and distribution of fossils, sediments and flowstones within the Dinaledi Chamber. The distribution of the different geological units and flowstones is shown together with the inferred distribution of fossil material.
The fossils came into the cave at the time of the deposition of the unit 1, 2 & 3 sediments via the chamber entrance at top right. Unit 1 represents early sediments which contain only some rodent fossils. Unit 2 represents sediments attached to side wall by flow stone, i.e. remnants of early deposits that do contain fossil bones of Homo naledi. Unit 3 represents rubble sediments containing most fossil bones.

Dinaledi skeletal specimens. The figure includes approximately all of the material incorporated in this diagnosis, including the holotype specimen, paratypes and referred material. These make up 737 partial or complete anatomical elements, many of which consist of several refitted specimens. Specimens not identified to element, such as non-diagnostic long bone or cranial fragments, and a subset of fragile specimens are not shown here. The ‘skeleton’ layout in the center of the photo is a composite of elements that represent multiple individuals. This view is foreshortened; the table upon which the bones are arranged is 120-cm wide for scale.
