It is closely related to the similar Vervet, Malbrouck, Tantalus and Green (Sabaeus) monkeys, which are sometimes treated as subspecies and sometimes as separate species in the Chlorocebus genus. They were all previously called Cercopithecus aethiops and the name Vervet or African Green was used for the whole species. Even now the name Vervet is often used for Chlorocebus aethiops and the Grivet treated as subspecies C. a. aethiops while the Vervet is C. a. pygerythrus.

Grivets have longer white facial hair and browner head and back fur than Vervets which are slightly greyer and are native to the remainder of East Africa (with some overlap) through to eastern South Africa. The Bale Mountains Vervet (C. djamdjamensis) from Ethiopia has longer, darker fur, a big white beard and no white brow. Other species (former subspecies) of Chlorocebus are native to west, central and southwest Africa. ("Vervets" including Grivets/others have also been introduced to Caribbean islands.)
