Tympanocryptis pinguicolla, also known as Victorian grassland earless dragon, is a species of lizard in the family Agamidae. It is one of a documented species of a relatively small dragon belonging to the genus Tympanocryptis.

T. pinguicolla is endemic to the state of Victoria in southeastern Australia. As with the other grassland earless dragons, it is restricted to areas of temperate grassland with tussock and smaller grasses. Very little of this habitat remains in Victoria due to the heavy degradation and conversion of this habitat in the past, which has contributed to the species’ endangerment.
