World Monkey Day

Animal Awareness Days

Celebrate World Monkey Day with us by learning more about monkeys, the threats they face, and how you can help them.

World Monkey Day (also known as Monkey Day and International Monkey Day) is a celebration of all monkeys, along with all other simians, including apes, tarsiers, and lemurs.

When is Monkey Day?

World Monkey Day is held every year on the 14th of December. This international monkey day is the perfect opportunity for conservationists, wildlife organisations, and individuals around the world to reflect on the plight of monkeys who are cruelly kept as pets, forced to entertain crowds in street performances, and made to perform for social media videos.

It’s also a chance to celebrate monkeys, showing people their unique characteristics and mannerisms.

How was World Monkey Day started?

World Monkey Day was first celebrated in 2000. A university student named Casey Sorrow started it as a madcap celebration with friends. As Sorrow and his friends made Monkey Day a tradition, it grew in notoriety. Now, this unofficial international holiday is celebrated worldwide.

5 facts about monkeys

  1. All monkeys are primates but not all primates are monkeys. The main difference between the two is their tail. Most monkeys have tails while apes and other primates do not.
  2. Barbary macaques are the only wild primates in Europe. They live on the island of Gibraltar, where a small population was introduced hundreds of years ago.  
  3. Pygmy marmosets are the world’s smallest monkeys, weighing just over 100 grams. Mandrills are the world’s largest monkeys, weighing around 35 kilograms.
  4. Monkeys are highly social, sentient beings. Their relationships with family and friends are vital for their wellbeing.
  5. In Indonesia, monkeys are sometimes trained to dance for the entertainment of humans. They undergo brutal training methods including being starved, having their teeth pulled out, and suffering physical abuse

Are monkeys endangered?

More than half of the world’s primates — including monkeys, apes, and lemurs — face extinction. Here are some of the threats that are endangering monkey populations.

Habitat loss and destruction

Monkey habitats are being destroyed to make space for agriculture, logging, and infrastructure. This means monkeys have less space in which to live, find food, and find a mate.

Illegal pet trade

Monkeys are being taken from the wild for the illegal pet trade and for entertainment purposes. They are used to create social media content or to perform as part of dancing monkey troupes.

Hunting

In some parts of the world, monkeys are hunted as food. Their body parts are also used in traditional medicine.

How to celebrate World Monkey Day

  • Take steps to stop the exotic pet trade. Report pictures of exotic pets on social media. If there is no option for "animal cruelty", then select the closest category.
  • If you see pictures of exotic pets on social media, don’t engage with them in a way that the algorithm could see as positive. Don’t comment, like, share, or tag others as this could drive more traffic to the posts and associated profiles.
  • Raise awareness of why wild animals should never become pets, even if they were bred in captivity. Create your own post or share ours to highlight this issue.
  • Support projects — like World Animal Protection’s monkey rescue project — where we’re taking monkeys from dancing monkey troupes. We’re working to rehabilitate these traumatised animals, providing food and veterinary care, before releasing them back into their natural home.  
  • Join our campaigns to push organisations and governments to safeguard animals and the habitats they rely on.
  • Sign up to our newsletter to find out about new ways you can help.

Many animals need your help. Find out about other animal awareness days.

Monkey FAQS

How many bananas can a monkey eat in a day?

Monkeys don’t actually eat bananas in the wild unless they’re close to human habitat. Monkeys eating bananas is a myth propagated by zoos and social media. You may see monkeys eating bananas on TikTok videos but, behind these videos, there is often a story of animal exploitation.

What do monkeys do all day?

Monkeys spend time grooming each other to strengthen troop bonds. They use tools, like small stones, to access food sources and engage in play, chasing one another and play-fighting.

Can monkeys eat meat?

Monkeys can eat meat but most primates rarely do. Meat eating is most common in capuchins, baboons, bonobos, and chimpanzees.

Can monkeys speak?

Monkeys can’t speak but they do communicate through facial expressions and vocalisations.

Mother and baby monkeys grow their bond through exaggerated facial expressions and long mutual gazes, like in a human child-parent relationship.

Monkeys also make a variety of sounds, like screams, howls, and calls. Baby monkeys who have experienced trauma show long-term effects in how they vocalise their emotions, producing noisy screams.

Can monkeys cry?

Monkeys don’t cry in the same way as humans do. They don’t produce tears but they can communicate their distress. When stressed, some monkeys will scratch themselves and when sad, they can produce vocalisations that include whimpers, coos, and screams.
