8 Largest Zoos in the World

So what is the largest zoo in the world? The answer to this question depends on what criteria is used for the term “large”. Are we measuring the number of species held in captivity or the total land area of the zoo. If we consider only the later the Red McCombs Wildlife in Texas with its 12,000 acres could be considered the biggest zoo in the world. But is has only 20 different animal species and is more of a wildlife preserve than an actual zoo. Just considering the number of species however also doesn’t seem to fit the bill.

This list therefore considers both these features to determine which is the largest zoo in the world.

Nebraska’s number one paid attendance attraction, the Henry Doorly Zoo in Omaha is home to about 17,000 animals of 962 species. It encompasses over 130 acres (53 ha) of land area. Although there are bigger zoos in terms of acreage or species numbers, none rank as high as the Henry Doorly Zoo if both these categories are combined. For this reason it is listed here as the largest zoo in the world. It also features the largest cat complex in North America, the world’s largest indoor swamp, the world’s largest indoor desert, as well as the largest glazed geodesic dome in the world.

    What happened to the massive Z!oo of Whipsnade in England. 650 acre with 5000 species set in big natural enclosures.Europes biggest

  2. Vickie says

    The San Diego Zoo should include the “The San Diego Safari Park”, they are in two locations, but it is one organization.

  3. CeCe says

    The best thing about the Henry Doorly Zoo (Omaha, Nebraska) is that even Omahans are impressed enough to get excited about purchasing their zoo membership every year. It doesn’t matter how many times you visit, there’s always something new and interesting to see, learn and experience.

  4. Mary says

    Henry Doorly Zoo is an amazing place. It really takes a couple days to explore. I would highly recommend it whether you are young or old. They also have a drive through safari park near Ashland that contains the only herd of a small prong horn deer in the world. The last time I was there, the herd was thriving and beginning to return from the edge of extinction. Totally amazing!!!

  5. Jen says

    I live 10 minutes away from the Henry Doorly Zoo in Nebraska, It is not only the largest, but it is the best zoo in the US. All we need now are pandas, and it will be the best tn the world!

  6. B says

    I visited the Beijing zoo a few yesrs ago and wsd horrified at the condition of the animals. Rlephants locked up in barns no ro toove, pandas
    That were filthy. The zoo itself was not a good place!!

  7. Brad says

    Then I guess they should include Wildlife Safari Park. It is also owned and ran by the Henry Doorly Zoo. I bet it would add quite a few animals and acres to the total.

    Many thanks for putting this list together, with lots of great details. very helpful for Bucket-list building, and also travel-planning. I’ve been to Toronto, and heading to New York in a few weeks, and both trips hadn’t considered their zoos. Sounds like an experience and I appreciate the insights.

  9. Karanja says

    I am taking 3 children of various ages to the Henry Doorly Zoo tomorrow. I know I shall leave tired and broke, but I have always loved zoo’s. My plan this summer is to see the full zoo…all the animals, and each species and sub-species. I think I can get it done in about 4 trips. I am from Kenya, East Africa, so I have some of these animals in the wild!!

  10. Karanja says

    @Kerry Martin, Make sure you go to MOMA if you like art, or at least the Botanical Gardens in Brooklyn.

  11. Mr Scotto says

    Thank you for this list. I love zoos and have visited many all over the world. But the largest collection of animals in the world actually belongs to a company that controls 11 parks and is based right here in the United States. Sea World Entertainment companies care for 86,000 animals. There is no other zoo organization that even comes close.
