The Powder Blue Tang, Acanthurus leucosternon, is a marine tropical fish belonging to the family Acanthuridae, or surgeonfishes. Its common names are powder blue tang and powderblue surgeonfish.

The fish can reach an average size of 23 cm in length. The body has an oval shape and is compressed laterally. Like other surgeonfishes, Acanthurus leucosternon swims with its pectoral fins. The caudal fin has a crescent shape. The fish has a "surgeon's scalpel," an erected part of the spine located at the base of the tail. The mouth is small and pointed in a beak-like manner with tiny and sharp teeth for reaching narrow spaces of food.

Its diet consists of meaty foods, as well as herbivorous marine seaweed and algae.
