Amalosia lesueurii, commonly known as a sigma  or Lesueur's velvet gecko, is a species of gecko, a lizard in the family Diplodactylidae. The species is endemic to Australia.

Etymology
The specific name, lesueurii, is in honor of French naturalist Charles Alexandre Lesueur.

Geographic range
A. lesuerii is found near the eastern coastline of New South Wales and Queensland.
