Causus lichtensteinii is a species of venomous snake in the subfamily Viperinae of the family Viperidae.

[4][5] The specific name, or epithet, lichtensteinii, honors German herpetologist Martin Hinrich Lichtenstein.

The back of the neck has a characteristic white V-shape while the throat is black with yellow bands.

[3] C. lichtensteinii is found from Guinea and Liberia eastward through Ghana to Nigeria, Cameroon, Equatorial Guinea, the Central African Republic, south to northern Angola, DR Congo and northwestern Zambia, and east to Uganda and western Kenya.

[2] The type locality is listed as "Côte-d'Or " [= Gold Coast, now Dominion of Ghana].

When disturbed it puts on a hissing and puffing threat display similar to other members of the genus.
