Ctenophorus decresii, also known commonly as the tawny dragon, tawny crevice-dragon, or tawny rock dragon, is a species of lizard in the family Agamidae. The species is endemic to Australia.
C. decresii is known for its variations in throat colours which change based on environmental conditions. Its primary food sources consist of both vegetation and invertebrates, and it prefers to live in rocky habitats. The average snout-to-vent length (SVL) of the species is 80.76 mm (3.180 in), with larger individuals being around 89 mm (3.5 in) and smaller individuals around 72 mm (2.8 in). The optimal time for mating in this species is two to three weeks after the females emerge from hibernation. Eggs are typically laid from September to October with most of them being laid earlier in the period.
