The Bald Uakari (Cacajao calvus), also known as the Red Uakari or Bald-headed Uakari, is a distinctive red-faced monkey found in swampy forests in Brazil, Peru, and Colombia. The species is considered "near threatened" by the 2004 World Conservation Union (IUCN) Red List because of hunting and the destruction of its habitat.[2]

It has little fur on the face, with bright red facial skin a sign of good health, enabling it to choose the healthiest (most red-faced) to mate with. It has long, thick, white or red body fur with short, bushy tails. It is on average 55 cm long and weigh around 3,000 grams, with 15 cm tails. It usually lives around 20 years.

The Bald Uakari feeds mainly on seeds and flowers, and some small animals.

It lives in mixed groups of between five and 30 members, spending most of its time on the ground searching for seeds, and at night sleeping in trees for safety. The breeding season is between October and May. The female encourages the male to mate by releasing an attractive scent. The gestation period is unknown.
