The Blotched Blue-tongued Skink ("Tiliqua nigrolutea") is a reptile with a long blue tongue.

The lizard is about 35 cm long and is found in woodland. It is an Omnivore with a diet consisting of leaves, flowers, slow moving invertebrates, and small vertebrates. It has heavily lidded eyes that are well protected. The anus can excrete a foul smelling musk. They are found on Tasmania and south eastern parts of Australia. Blotched blue-tongues emerge from hibernation in late September (in Tasmania), mate in late October, and babies are born in autumn (March-April). These large skinks are viviparous (give birth to live young) and long-lived (anecdotally 20 years or more).

The Blotched Blue-tongued Skink is among the animals identified from the Pleistocene fossil sites of the Naracoorte Caves.
