Barbour's day gecko (Phelsuma barbouri) is a species of lizard in the family Gekkonidae.

Barbour's day gecko feeds on insects and nectar.

[citation needed] P. barbouri inhabits the highlands of central Madagascar in the Ankaratra Mountains, at altitudes of 1,600–2,640 m (5,250–8,660 ft).

[1][4] In contrast to other lizards of the genus Phelsuma, P. barbouri is terrestrial and typically lives on stones on the ground or on rocks in savanna habitat.

[citation needed] Adult females of P. barbouri glue their eggs under stones.

In captivity, it can be fed crickets, wax moths, fruit flies, mealworms, and houseflies.
