It measures about 40-55 centimetres (16-22 inches) tall, excluding its tail. Its tail measures 50-75 centimetres (20-29 inches) in length.

The Diana Monkey is from west Africa, in the countries of Sierra Leone, Guinea, Liberia, and the Ivory Coast. It prefers forests.

It is diurnal, active during the day.

It feeds in the trees, and rarely comes to the ground. It eats fruit, flowers, leaves, seeds, and insects. Its predators include eagles, leopards, and chimpanzees.

The Diana Monkey lives in social groups with one dominant male and several females, and their young. Females are pregnant for about 5 months, before giving birth to one live young. The baby is born with its eyes open and with some fur. It develops quickly and becomes mature by 3 years of age. Daughters remain in the group, whereas sons leave the group to form their own group.

The Diana Monkey may live for up to 20 years.
