Protemnodon is an extinct genus of megafaunal macropodids that existed in Australia, Tasmania, and New Guinea in the Pliocene and Pleistocene.

Recent analysis of mtDNA extracted from fossils indicates that Protemnodon was closely related to Macropus.

[3] A 2024 review of the genus recognized seven valid species, including three new ones: P. chinchillaensis and P. hopei were considered junior synonyms of P. otibandus and P. tumbuna respectively.

[4] Based on fossil evidence, Protemnodon is thought to have been physically similar to wallabies, but generally larger and more robust.

[5] Some studies show that Protemnodon species ranged from efficient hoppers of dry open habitats (such as P. viator) to slower, more quadrupedal forest dwellers (like P. tumbuna),[4] while others have found that even species such as P. viator were very inefficient hoppers and primarily quadrupedal.
