Propalorchestes is a fossil genus of palorchestid marsupial that existed in Australia during the Miocene epoch.

The genus is probably ancestral to Palorchestes and resembles Ngapakaldia, another palorchestid that existed during the Miocene epoch.

[1] Evidence for the transitional connection between earlier and later phylogenies was discovered amongst the Riversleigh fauna, including a more complete maxilla within the unworn dentition of a juvenile.

[2] The marsupial appears to have existed from the early to mid Miocene in material obtained in north-eastern Queensland, in fossil deposits at Riversleigh.

[2] A largely complete cranium, providing anatomical evidence of the rostral morphology that distinguished the lineage of Propalorchestes and Palorchestes from similar groups of the diprotodont order of marsupials.
