The malbrouck (Chlorocebus cynosuros) is an Old World primate from Africa that belongs to the genus Chlorocebus. The species is sometimes classified as a subspecies of the vervet monkey (C. pygerythrus), or of the widespread grivet (C. aethiops).

The malbrouck is a slim, agile primate with long limbs and a long tail. The fur is olive-grey. The breast and underparts are white, as well as the cheeks and eyebrows, which surround the bald, pale-blotched face. The eyes are brown. The genitals are brightly colored; the scrotum of the male is blue, the penis is red. Males are about 20% larger than females.

The malbrouck is found in central and south-central Africa, ranging from the Albertine Rift in DR Congo west to the Atlantic coast and south to northern Namibia and Zambia west of the Luangwa River. It lives in marshy forest, savanna-forest and montane forest up to an altitude of 4,500 m (14,750 ft). My images in this gallery come from Khwai Camp Botswana - Okavango Delta.
