About the Zoo & Wildlife

Lincoln Park Zoo, also known as Lincoln Park Zoological Gardens, is a 35-acre (14 ha) zoo in Lincoln Park, Chicago, Illinois. The zoo was founded in 1868 and is the second oldest zoo in the United States. It is also one of a small number of zoos to offer free admission. The zoo is an accredited member of the Association of Zoos and Aquariums (AZA). In 2019 it also became an accredited arboretum. Lincoln Park Zoo is home to a wide variety of animals. The zoo's exhibits include big cats, polar bears, penguins, gorillas, reptiles, monkeys, and other species totaling about 1,100 animals from some 200 species. The Lincoln Park Zoo was long home to a burr oak tree which was estimated to more than 250 years old. The tree was cut down on May 2, 2023, due to poor health. Thirty-six scions of the tree were grafted onto root stock and are growing at the Morton Arboretum.
