Chalarodon madagascariensis is a species of Malagasy terrestrial iguanian lizard native to western, southern, and south eastern Madagascar.

The species inhabits mainly coastal, semi-arid to arid regions and almost entirely open, or very sparsely vegetated habitats with sandy soil in the province of Toliara, and in the southwestern provinces of Fianarantsoa and Majunga in the southwest of Madagascar.

This species is widespread in western, southern, and eastern Madagascar.

[1] Calarodon madagascariensis is most easily distinguished from C. steinkampi by its keeled gular and ventral scales, which are unkeeled in the latter species.

In addition to insects, sometimes plants are ingested, particularly in the form of leaves and roots.
