The saltbush Morethia skink (Morethia adelaidensis), or more commonly referred to as saltbush skink, is a species of skink found in Australia. They are part of an 8 species genus of Morethia, which are all endemic to Australia. Akin to other members of the Morethia genus, saltbush skinks feature transparent disks as eye covers and eyelids which are stationary, along with specialised limbs which enable quick traversal of sand dunes. Taxonomically, the species was first classified by German explorer Wilhelm Karl Hartwig in 1871.
