The Tana Mangabe ( Cercocebus galeritus ) is a highly endangered primate species from the family of the vervet monkeys (Cercopithecidae). Together with the olive , gold-bellied and Sanje mangabe , it used to be combined into one type, the hood indication .

Tana mangaben are slender, long-tailed primates. Their fur is yellowish-gray in color, with the underside being a little lighter. At the top of the head there is a dark-colored head of hair, the rear half of the tail is also darkly colored.

These animals are found exclusively in the valley of the Tana River in eastern Kenya . Their habitat are river forests. They are diurnal and can be found both on the ground and in the trees.

They live in groups of 15 to 30 animals, which are composed of several males, numerous females and their young animals. The males lead the group, among other things by loud screams, which also make other groups aware of their own location.

Tana mangabians are opportunistic omnivores that eat fruits, seeds and other parts of plants, but also insects and small vertebrates such as lizards and frogs.

Tana mangaben are among the most threatened primates. The total population is less than 1600 animals, which are divided into around 50 smaller populations. The total habitat is estimated to be only 26 square kilometers. In 1976 a protected area was set up in which 50 to 60 percent of the total population live; but make urban sprawl, deforestation and planned hydropower plants pose serious threats. The IUCN lists the species as "critically endangered" ( endangered ).
