The cave hyena (Crocuta crocuta spelaea and Crocuta crocuta ultima), also known as the Ice Age spotted hyena, are paleosubspecies of spotted hyena known from Eurasia, which ranged from the Iberian Peninsula to eastern Siberia. It is one of the best known mammals of the Ice Age and is well represented in many European bone caves. It preyed on large mammals (primarily wild horses, steppe bison and woolly rhinoceros), and was responsible for the accumulation of hundreds of large Pleistocene mammal bones in areas including horizontal caves, sinkholes, mud pits, and muddy areas along rivers.

Genetic evidence from the nuclear genome suggests that Eurasian Crocuta populations (including the west Eurasian Crocuta crocuta spelaea and Asian Crocuta crocuta ultima) were highly genetically divergent from African populations (having estimated to have split over 1 million years ago), though the lack of clear separation between mitochondrial genome lineages suggests that the two populations interbred for some time after the initial split.^[1] Some authors have suggested that the two subspecies should be raised to species level as Crocuta spelaea and Crocuta ultima.^[2]

The cause of the cave hyena's extinction is not fully understood, though it could have been due to a combination of factors, including human activity, diminished quantities of prey animals, and climate change.^[3]
