Ctenodactylus gundi ranges from eastern Morocco, through Algeria and Tunisia, to western Libya. It occurs mainly on the southern slope of the Atlas Mountains, where it has been recorded at altitudes from 230-2,900 m. The limit between the distribution of this species and C. vali in the west of the Saharan Atlas varies according to precipitation, with C. gundi disappearing in dry periods, and C. vali then occupying these areas.
