Liolaemus is a genus of iguanian lizards, containing many species, all of which are endemic to South America.

[2] Members of the genus Liolaemus form a dominant part of the lizard fauna of the southern part of the continent of South America, and vary considerably in size (45–100 millimetres or 1.8–3.9 inches snout–vent length) and weight (3–200 grams or 0.1–7.1 ounces).

Liolaemus species are found in the Andes and adjacent lowlands, from Peru to Tierra del Fuego,[3] at altitudes that can exceed 4,500 metres (14,800 ft).

[4] Liolaemus is by far the largest genus of the liolaemid lizards, which are traditionally treated as subfamily Liolaeminae within the Iguanidae but more recently were proposed for upranking to full family Liolaemidae.

Some species of Liolaemus have been recently kept as pets, and as many of them originate from regions that experience cold conditions, they are named "snow swifts".
