Podarcis virescens, also known by its common name as Geniez's wall lizard, is a lizard species of the Lacertidae family. Podarcis virescens is commonly found in the Iberian Peninsula, including Spain and Portugal. The lizard's name is derived from Latin due to its color turning from a usual brown color to green during the spring. Podarcis virescens are a moderate sized lizard and robust in build. Colors vary during seasons and range between individuals from white, brown, green, and black. Podarcis virescens have been found in villages and other human-populated areas in Spain and Portugal at elevations of around 840 meters.

Podarcis is a genus of lizards in the family Lacertidae. Its members look very similar to lizards of the genus Lacerta, to which they were considered to belong until the 1970s. While similar externally and ecologically, Podarcis form a distinct group differing from Lacerta by the construction of the skull and the hemipenis, and by the processes of the caudal vertebrae. They are commonly known as wall lizards. They are native to Europe and northern Africa, and most species are restricted to the Mediterranean region. Wall lizards diversified and hybridized during the Messinian salinity crisis. The Italian wall lizard and the common wall lizard have been introduced to North America, where they have become intermediate hosts for some Acuariidae larvae.
