Yalkaparidon is an extinct genus of Australian marsupials, first described in 1988 and known only from the Oligo-Miocene deposits of Riversleigh, northwestern Queensland, Australia.

Numerous isolated teeth and jaw bones of Yalkaparidon are known, but only a single skull (of Y. coheni) has so far been recovered.

These specimens of Yalkaparidon exhibit a melange of characters: the molars are zalambdodont (a distinctive tooth type also found in the marsupial mole Notoryctes, the living placental 'insectivores' Solenodon, tenrecs and golden moles, as well as a number of fossil groups); the incisors are very large and hypselodont (open-rooted and hence ever-growing, similar to those of rodents); the basicranial region of the only known skull is very primitive, somewhat similar to those of plesiomorphic bandicoots.

However, Frederick Szalay suggested in his 1994 book 'Evolutionary History of the Marsupials and an Analysis of Osteological Characters' that Yalkaparidon is indeed a diprotodontian (as evinced by its incisors), albeit one that retains a highly primitive basicranium.

The exact function of its unusual dentition remains obscure, and suggestions that it may have fed on worms (based on the similarities of its molars to those of worm-eating tenrecs), caterpillars or eggs are tenuous.
