In 2013, The National Institutes of Health (NIH) officially ended federally-funded biomedical research on chimpanzees. As the National Chimpanzee Sanctuary, Chimp Haven was designated as the place where hundreds of chimpanzees formerly used in biomedical research would retire.

Since then, Chimp Haven has embarked on a determined effort to bring every eligible chimpanzee waiting in research facilities across the country home to the sanctuary as quickly as possible.

Now, we’ve reached a pivotal moment.

With some of the last remaining eligible chimpanzees still waiting their turn to come to the sanctuary, we’ve reached the final stretch of a $20 million effort to expand the sanctuary to make room for them.

Completing the Welcome Them Home sanctuary expansion will be a historic moment for chimpanzees in our country. Scroll to learn how you can join us in welcoming them home – for good.

“Chimp Haven cares for chimpanzees retired from medical research, enabling them to enjoy a healthy, happy life, living in engaging, enriched habitats and in communities with other chimpanzees. I hope you will support Chimp Haven and help provide for these chimpanzees as they live out their days in the sanctuary’s excellent care.”

In addition to new housing for chimpanzees still waiting in research facilities, the Welcome Them Home expansion will provide much-needed sanctuary upgrades to ensure Chimp Haven can meet the needs of our rapidly growing family for years to come.

There are a number of transformational gift and naming opportunities available. We invite you to be part of this historic effort by donating today or contacting Chimp Haven’s Chief Development and Marketing Officer, Taylor Johnson at

When you help Chimp Haven complete its historic sanctuary expansion with a gift of $500 or more, you’ll symbolically purchase a parcel of land in one of three new multi-acre chimpanzee habitats.

When Hamlet arrived at the sanctuary in 2006, many who worked with him during his life in research thought he would never be able to live in a group with other chimps. Hamlet, like other retirees who arrive at Chimp Haven, was described as “hyper aggressive.”

Chimp Haven’s Behavior and Enrichment team is dedicated to successfully matching every Chimp Haven retiree with a social group. With a fresh start, new settings, space to move around, and a variety of chimp personalities to choose from, they are able to find a perfect match for every retiree.

Today Hamlet lives in a group of 21 chimps, including six of our newest arrivals. In 2019, they bonded over exploring one of Chimp Haven’s forested habitats.

At Chimp Haven, chimps retired from research experience the joys they would have enjoyed in the wild: climbing trees, living in large, bonded social groups, eating their favorite fruits, running, playing, exploring, and — best of all — choosing how they spend their days.

We want every chimp to experience life at sanctuary, and now is our moment. You can be part of this historic effort to bring them home once and for all.
