Phoboscincus garnieri, also known commonly as Garnier's giant skink and Garnier's skink, is a species of lizard in the family Scincidae.

[2] The specific name, garnieri, is in honor of French mining engineer Jules Garnier.

It is secretive, hiding in holes in the ground or beneath logs and rocks, and hunting in dense vegetation and litter.
