Sahara horned vipers are among the most abundant and easily distinguishable of the venomous snakes of the North African and Middle Eastern deserts. Cerastes cerastes is generally distributed all across North Africa, including southwestern Arabia and southwestern Israel. Common in the Sahara desert, it is most frequently found between Egypt and Morocco. Its range extends to southward to northern Mali, Niger, northern Chad, Sudan, and Mauritania.
Although records are rare in the southern Saharan borderlands, this snake has been reported within the Sahel, the sub-steppe region of the Sahara. Interestingly, C. cerastes is also known to inhabit the deserts of the eastern Sinai, coexisting with the Arabian horned viper, Cerastes gasperetti mendelssohni.
