Anolis ferreus, the Morne Constant anole, also known as the Marie-Gallant anole, is a species of anole lizard that is endemic to the island of Marie-Galante, which is part of Guadeloupe in the Caribbean Lesser Antilles.

[2][3] It has been recorded as an escapee in Fort Myers, Florida, but does not appear to have become established.

It has a yellow-green dorsal surface, and a blue-gray head with yellow around the eye.

Males have prominent tail crests.

[2] It is primarily active during the middle part of the day, retreating to high perches in the late afternoon.
