The Denver Zoo is an 80-acre facility located in City Park of Denver, Colorado. Founded in 1896, it is owned by the City and County of Denver and funded in part by the Scientific and Cultural Facilities District (SCFD). It is the most popular paid attraction in the Denver metropolitan area.

The Denver Zoo was started with the donation of an orphaned American black bear. With the construction of Bear Mountain, it became the first zoo in the United States to use naturalistic zoo enclosures rather than cages with bars. It expanded on this concept with Primate Panorama, featuring huge mesh tents and open areas for apes and monkeys, and with Predator Ridge, which has three separate areas through which animals are rotated so that their overlapping scents provide environmental enrichment. Toyota Elephant Passage, which opened on June 1, 2012, is divided into five areas for rotating the various species.

The Denver Zoo houses species from all over the world, including hoofed mammals, carnivorous mammals, primates, pachyderms, birds, reptiles, and fish. The zoo's animal collection contains 4,125 specimens representing 613 unique species. The zoo is laid out in a large loop, with exhibits both inside and outside the loop.
