The dusky toadlet (Uperoleia fusca) is a species of Australian ground-dwelling frog that inhabits coastal areas from just north of Sydney, New South Wales to mid-northern Queensland.

The flanks of this species are normally bluish in colour, giving it a dusky appearance.

This species is very similar to the smooth toadlet, (Uperoleia laevigata) and differences between the two are discussed on that page.

Frogs call during spring and summer, normally from dams, swamps, roadside ditches, or flooded grassland areas.

Males call from the bases of grass clumps close to the water's edge.
