Litokoala is an extinct genus of marsupials, and along with Nimiokoala, is closely related to the modern koala.

The genus lived about 10–16 million years ago in the middle Miocene Riversleigh of Queensland.

Cranial adaptations are intermediate between the extant common brushtail possum and koala, with minor divergence from either.

This genus and Nimiokoala are similar in most anatomical features so far as is known, except Litokoala possessed a superficial messateric process, while Nimiokoala had "more marked basiooccipital-basisphenoid flexion and a more extensive posterior attachment of the pterygoid",[5] which make these features basal in their taxonomical position in relation to the Phascolarctos.

Only partial fragments are known, with only the posterior section of the zygomatic process known from the L. kutjamarpensis skull.
