Anolis callainus, the Dominican green anole, Northern Hispaniolan green anole, or Hispaniolan green anole , is a species of lizard in the family Dactyloidae.

The species is endemic to the Dominican Republic, where it is found throughout the eastern half of the country.

[2] Previously considered conspecific with the Tiburon green anole (A. chlorocyanus), a 2020 study restricted chlorocyanus to the population found in western Haiti, and redescribed the eastern Dominican Republic population as a new species, A.

[3] It is very similar to the North American species, the green anole (Anolis carolinensis), but males have a light blue throat flap, instead of red.

Females and juveniles may have darker green stripes lining the sides of their bodies, but males are often a pure bright green color.
