Rankinia is a genus of small agamid reptiles. As currently delineated, it is monotypic, containing only Rankinia diemensis (Gray, 1841), also known as the mountain heath dragon or mountain dragon. It is endemic to Australia.
They do not climb very high, relying instead on camouflage to evade predators. but can be up to 9. They have a row of enlarged spinose (spikey) scales on each side of the tail bases.
The mountain dragon appears similar to the jacky dragon, but can be much redder, and the inside of its mouth is pink (compared to the yellow of the jacky dragon).
They breed in summer, laying 2–9 eggs in a burrow.
