Azilestes ("Mas-d'Azil robber") is a genus of probable zhelestid eutherian mammal, a family consisting of small herbivores, that was discovered in the early Maastrichtian Grès de Labarre Formation of France. It is a monotypic genus, with only type species A. ragei being known. Only one specimen, the holotype described in 2021, is known. It consists of a partial dentary with teeth.

Certain aspects of Azilestes's dental anatomy are heavily convergent with later groups of herbivorous mammals, including Glires, though phylogenetic analysis suggests a position within the Zhelestidae. It possesses bunodont molars, enlarged postfossids and hypoconids, an interradicular crest and radicular grooves, a unique combination among Cretaceous eutherians.
