Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 cm (6 inches) long, its tubercules are enlarged and give the species a spiny armoured appearance.

The species was first described by Carl Linnaeus in 1758. It is also known as Moorish gecko, crocodile gecko, European common gecko, and, regionally, as tarantola, osga, salamanquesa, and dragó.
