Mabuya is a genus of long-tailed skinks restricted to species from the Americas. They are primarily carnivorous, though many are omnivorous. The genus is viviparous, having a highly evolved placenta that resembles that of eutherian mammals. Formerly, many Old World species were placed here, as Mabuya was a kind of "wastebasket taxon". These Old World species are now placed in the genera Chioninia, Eutropis, and Trachylepis.
