Lilford's wall lizard (Podarcis lilfordi ) is a species of lizard in the family Lacertidae. The species is endemic to the Balearic Islands, Spain.
Its natural habitats are temperate Mediterranean-type shrubby vegetation, rocky areas, and rocky shores. Originally distributed throughout the Balearics, the introduction of alien species which started with the Romans has confined the species to the uninhabited islets around the major islands, on almost each of which a local subspecies has evolved. It is threatened by habitat loss.
P. lilfordi is named in honour of Thomas Powys, 4th Baron Lilford, a British ornithologist who studied the fauna of the Balearics.
Lilford's wall lizard grows to a maximum snout-to-vent length of 8 cm (3 in) but adults are usually a little smaller than this. The tail is about 1.8 times as long as the body. It is a robust streamlined lizard with a short-head and rounded body with smooth, unkeeled scales. The dorsal surface is usually greenish or brownish but varies much between different island subpopulations. There is usually a pale dorso-lateral stripe and there may be several dark streaks or three dark lines running along the spine. The flanks may be slightly reticulated and the underside is white, cream or pinkish. The throat may be blotched with darker colour. Juveniles sometimes have a blue tail.
Lilford's wall lizard is native to the islands of Menorca and Mallorca in the Balearic Islands, the Cabrera Archipelago to the south of Mallorca, and the neighbouring rocky islets. However it has been extirpated from the two large islands and is now only present on the islets.
P. lilfordi is found at low altitudes. It is a mainly ground-dwelling species and largely inhabits rocky areas and scrubland, although it is found in woodland on Cabrera.
