'''''Zoo Tycoon''''' is a series of video games (mostly for PC) where the player is given the task of managing a zoo, keeping both its guests and animals happy and healthy, [[VideoGameCrueltyPotential or not]]. The first game was released in 2001, with expansion packs adding dinosaurs (''Dinosaur Digs'', 2002) and marine life (''Marine Mania'', 2002) to the mix.

The sequel, ''Zoo Tycoon 2'' (2004), brought the game into 3D and changed several mechanics, while still following the same set of ideas. This game also had expansion packs: ''Endangered Species'' (2005), ''African Adventure'' (2006), ''Marine Mania'' (2006), and ''Extinct Animals'' (2007).

A reboot for the {{Xbox One}} and {{Xbox 360}} was released in 2013, and in 2014, an app was announced for Windows 8 and Windows Phone.

!!This game provides examples of:

* AnEntrepreneurIsYou
* AnimalGenderBender:
** In the first game, male and female ostriches look the same, whereas in real life the males are black and the females brownish.
** Also in the first game, female kangaroos are incorrectly just as red as the male ones.
* AnimalsLackAttributes: Animals in [=ZT2=] squat to poop, but nearly all have no orifice to poop through (the hippos do have an anal dot). Aurochs cows in the "Extinct Animals" expansion have a visible udder, but it doesn't have any teats.
* ArtificialStupidity: Many, in both the original and in the sequel.
** The animal's inability to reach a certain pile of food or food troughs for absolutely no reason. (Though sometimes that message will show up but when you click over to check it out the animal is eating/drinking from the very thing they supposedly couldn't get to.)
** Zookeepers being unable to reach a animal/food dish/poo for no reason at all. Instead choosing running around the sides of the exhibit.
*** It should be noted that this is sometimes the player's fault if they forgot to add a staff gate (in the sequel anyway, as gates are automatically added to enclosures in the original) or if the gate is blocked by another object, but just as often the keeper simply has no excuse.
** In the original game. If you put 500 scientists and a dinosaur on an island, the scientists will completely ignore the dinosaur which is eating them up. Meanwhile, the only scientist in your park who isn't on the island will be trying to get there to put the dinosaur back in a cage. Marine Biologists are even worse. Fortunately this was somewhat fixed for the sequel ''Extinct Animals''.
** Zoo guests are annoyingly dimwitted. You can build a zoo so a whole food court + bathrooms is within easy reach at all times, but there will always be at least one angry guest with a critical level need because they decided that riding a zoo ride/making a wish/talking to another guest was more important than taking care of that need before it got too high. Of course, the zoo is what they blame. In other words, [[TakeThat a perfect representation of reality.]]
* AwesomeButImpractical:
** Some of the best user-created zoos in the sequel use dozens of hyper-realistic mods that are used to achieve a realistic looking zoo. Unfortunately, guests cannot see through fences that they should or animals cannot get around due to too many rocks.
** Dinosaur exhibits seem appealing, but they take a lot of money to build and maintain. They also require a lot of room you could have used on something else, which can be especially problematic since the size of the exhibit can negatively impact guest happiness: If they don't see lots of happy animals, their happiness score starts to decline.
** Yetis are prohibitively expensive and are very picky about their exhibit.[[note]]And for good reason: they're adapted to the thin air of the Tibetan mountains, and have difficulty acclimating to the elevation of the average zoo.[[/note]] In spite of their mythical appeal, they aren't popular to guests because of their tendency to hide in their shelter. Raising a yeti is akin to a SelfImposedChallenge.
* ArtisticLicenseBiology:
** Occasional gaffes in animals' descriptions (Galapagos giant tortoises on the mainland?) or the criteria of a challenge (jaguars, whose breeding range extends into Mexico, not counting as a North American species).
** Animals do not breed according to certain seasons, instead they breed randomly without any pattern to it. Species where normally the females would give birth all around the same time don't.
** Most animals have two young at a time at the most, even if they are lions or other animals that usually have more than that.
** In most cases the female animals are not smaller than the males.
** Your birds and crocodiles are said to have given birth when they have young, instead of laying an egg. The dinosaurs (with the exception of the hidden ''Triceratops'' in the first game, which lays eggs when the ''Dinosaur Digs'' pack is installed) correctly lay eggs.
** "Bengal tigers live in small groups." Wait, what?
** Baby penguins are simply a smaller version of the adult penguin model instead of a more accurate fluff ball.
** Black bears and grizzly bears can co-exist in the same exhibit, despite the two being enemies in real life.
* ArtisticLicensePaleontology:
** Some of the dinosaurs and other prehistoric creatures inhabit unrealistic biomes. You can, for instance, make a ''Stegosaurus'' happier by putting a ''glacier'' in its exhibit.
** Several extinct animals are also inaccurate in terms of behavior and/or appearance (the likely herbivorous oviraptorosaur ''Protarchaeopteryx'' is portrayed as a strict carnivore).
** Despite the extinct animals living in different biomes even within the game, every zoo from the city to the arctic have the fossils for every extinct animal. Needless to say, no animals, extinct or living, lived in every biome on Earth.
* BearsAreBadNews: If you sic the bears on the zoo guests anyway.
* BigBallOfViolence: Fights between animals are shown this way in the original.
* BoringButPractical:
** A lot of the animals available for adoption early on (such as peacocks or gazelles) aren't as interesting as later species, but they are very easy to please and will often have a lot of babies as a result. Since guests love baby animals, they can easily earn back a lot of donation money, and you can release the babies when they grow up for an extra fame boost.
** Low-mantinence animals like warthogs, giant anteaters; etc. They're not all that interesting to either players or visitors, but they fill up the species/exhibit quota for any scenario, and are necessary for any starting zoo. Warthogs in the first game are particularly useful for their [[ExplosiveBreeder breeding ability]], which will provide revenue in both increased attendance and selling off any overcrowding animals once the babies reach adulthood.
** In the first game,any animal suited to the environment the zoo is situated in. For early scenarios, grassland animals are a given, while later scenarios like the ones seen in the "Advanced" difficulty switch it up.
* CheatCode: ''Everywhere''. From "shift-4" for unlimited cash to the various ways renaming exhibits can unlock special animals to how aquatic-themed items react if you put them in a tank, there are little bonuses all over the place.
* ConservationOfCompetence: The ArtificialStupidity problems mentioned are more likely to manifest and worsen, the bigger your zoo is and the more guests who visit (which does make a certain amount of sense, as they are all drawing on your computer's resources, and thus have a fixed amount of "intelligence" between them).
* CreatureHunterOrganization: The Dino Capture Team.
* DumbDinos: The herbivorous dinosaurs in the first game don't bother to defend themselves from predators, even ones much smaller than they are. Averted in the sequel with the ''Utahraptors'' and ''Stokesosaurus'', who are smart enough to need enrichment and like to paint.
* EarlyInstallmentWeirdness:
** In the first game, the ''Triceratops'' does not start as an egg. ''Triceratops'' are also in an ExpansionPack as a non-hidden animal. If you install said expansion pack, it can cause your old ''Triceratops'' to be able to break out of their enclosures because the ExpansionPack changes what fences are compatible with the animal.
** The first game is the only one in the series where you cannot play as a zoo keeper.
* EasterEgg:
** You can unlock ''Triceratops'', mermaids, Bigfoot, and unicorns by doing certain things in the first game.
** Spinning the globe enough times in the sequel causes the entire population to scream loudly.
* EscapedAnimalRampage: Animals can be released by deleting a section of fence or they can escape on their own if you don't maintain damaged sections of fencing. Releasing the ''Tyrannosaurus'' in Dinosaur Digs can provide a little fun via Easter egg. If the ''T. rex'' destroys a one-person restroom you can see a person crying on the toilet (a reference to the lawyer's fate in ''Film/JurassicPark''.)
* EverythingsBetterWithDinosaurs: ''Dinosaur Digs'' in the first game and ''Extinct Animals'' in the second one.
* EverythingsBetterWithPenguins: and [[EverythingsBetterWithMonkeys monkeys]]. And yes, even {{bears|AreBadNews}}. And so on, and so forth.
** In the first game, placing an Emperor Penguin in an exhibit suited to it will make it [[spoiler: kill ''any'' other animal placed into the same exhibit, unless it's a penguin.]]
*** Parodied in the sequel with the Killer Penguins that can get dumped on you.
* ExpansionPack: Two for the first game and four for the second.
* ExplosiveBreeder: Warthogs, at least in the first game. They could have up to ''six'' in a litter, easily the fastest breeders in the game, and they would overcrowd very quickly.
* FantasyKitchenSink: Using the right expansion packs and Easter eggs, your zoo can include exhibits for bigfoot, yeti, mermaids, unicorns, and Loch Ness monsters.
* FollowTheLeader: ''Zoo Tycoon'' was one of many "tycoon" simulation games released during the time of VideoGame/RollerCoasterTycoon's popularity. However, the game was one of the few "tycoon" games that were '''[[TropesAreNotBad good]]'''.
** Zoo Tycoon itself would get a few imitators of its own, including ''SeaWorld Tycoon'' and the ''[[VideoGame/RollerCoasterTycoon RollerCoaster Tycoon 3: Wild!]]'' expansion pack, bringing this whole thing full circle.
* FossilRevival: In ''Extinct Animals'', you can hunt for fossils and bring them to life in an extinct research lab.
* GoneHorriblyWrong: In the second game, messing too much in the genetic lab minigame will result in a killer penguin: An [[UpToEleven even more psychotic]] [[PrehistoricMonster prehistoric]] rockhopper penguin from WesternAnimation/{{Madagascar}} (yes, possibly related to ''those'' penguins) complete with teeth, [[RedEyesTakeWarning red]] [[GlowingEyesOfDoom glowing]] eyes, and a taste for Tyrannosaurs and anything smaller. ''And you can't sell it. '''EVER'''''.
** Also, if someone tries to sell you a free penguin, [[MyGodWhatHaveIDone do not accept the offer]]. Unless you like them for some strange reason.
** Even worse, sometimes after you get the Killer Penguin, IT REPLACES THE SCIENTIST IN THE GENETIC LAB. Have fun sleeping tonight!
* GuideDangIt: In the first game, one of the goals of the Endangered Species scenario is to breed three different kinds of animals - the White Tiger, the Black Leopard, and the Okapi - before the time limit. While the former two breed fairly quickly, the Okapi are very shy and won't breed easily even with perfect conditions. Unless the player knew their animals, they wouldn't think to build the Okapi exhibit with any greater urgency than the other two, thus running out of time and losing the scenario because of doing things in the wrong order. The fact that the Okapi are the ''last'' of these animals to be researched put this scenario firmly in ThatOneLevel terriory.
* HerbivoresAreFriendly: Played irritatingly straight. Place a carnivore in an herbivore's exhibit and it's pretty much a death sentence for the latter, regardless of whether or not the herbivore can defend itself. This ranges from the mildly annoying but unsurprising (like crocodiles eating peafowl) to the absolutely ridiculous (''Protarchaeopteryx'', a dinosaur smaller than a turkey, effortlessly killing and eating ''Kentrosaurus'', a dinosaur the size of a truck and covered in gigantic spikes).
* HolidayMode: During the in-game Christmas and Halloween, you'll sometimes see Santa or a witch flying through the air.
** And on December 25th and October 31st, you can buy special objects (a Christmas tree and a Jack-o-Lantern).
** Guests' clothing can be changed to holiday-appropriate colors with the right EasterEgg.
* InNameOnly: ''Protarchaeopteryx'' in "Extinct Animals". What makes this example so strange is the fact that the fossil you revive the animal from is clearly the famous Berlin specimen ''Archaeopteryx'' meaning that they could have just made it "''Archaeopteryx''" instead. To make things worse, the original ''Protarchaeopteryx'' specimen [[http://www.nhm.ac.uk/resources/nature-online/life/dinosaurs/dinosaur-directory/images/%5Creconstruction/small/Protarchaeopteryx.jpg is actually complete enough to include in the minigame]].
* MajorInjuryUnderreaction: Reading the thoughts of a guest being attacked by an animal will show that their only reaction is "Ouch! I've been attacked by [animal]".
* MisplacedVegetation: Averted in [=ZT1=], as animals become unhappy if the plants in their exhibits are inappropriate to their native habitats.
* NeverSmileAtACrocodile: Crocodiles are included in both games. In [=ZT1=], once you complete all of the ''Dinosaur Digs'' campaigns or just rename an exhibit "Super Croc", it unlocks ''Deinosuchus'', which is basically, as the exhibit name implies, a giant crocodile.
** The second game also allows for ''Deinosuchus'' to either purchase, or create in the extinct research lab. Though unlike the real ''Deinosuchus'', it has spikes because [[RuleOfCool it looks cool or something]].
* NoFairCheating: Using the "SHIFT-4" cheat to get extra money will completely break one section of an exhibit's fencing or dirty a tank in the Marine Mania expansion.
* OOCIsSeriousBusiness: Instead of the free reign you have on exhibits in [=ZT2=], animals in the first game have a VERY SPECIFIC amount of trees, rocks, appropriate tiles they want in their exhibit. Putting just one extra water tile in and they'll produce a "sad/angry" face instead of a happy face.
* PteroSoarer: The "Pteranodon House" contains no ''Pteranodon''.
** There are some custom fan-mods of pterosaurs that vary in terms of accuracy.
* RaptorAttack: ''Velociraptor'' appears in the first game, and it's scaly. A scaly ''Deinonychus'' and ''Utahraptor'' and feathered ''Velociraptor'' appear in [=ZT2=]. The male ''Utahraptors'' have feathery crests on their heads.
* RealityIsUnrealistic:
** In real life zoos, peafowl are typically allowed to roam free, but in ZT2, free-roaming peafowl almost always send guests into a panic. There are ways around this, though.
** You can feed a number of live prey items to your carnivorous animals. In real life this was common in the past, but today most zoos have banned the practice of using live prey, for both ethical and safety reasons (it is unfair to the prey animal, as it does not have any chance of escape like it would in the wild - and because it's still alive, it is obviously going to fight back, which can lead to the predator animal being severely injured or killed).
* RealTimeWithPause: You can pause the game time and still make buildings or adopt animals.
* RunningGag: On the original game box art, a white mouse can be seen if you look closely. This continued with the two white mice (Zoey & Zeek) on the [=ZT2=]boxarts.
* SceneryPorn: In Zoo Tycoon 2, even subpar landscaping can lead to this. This also a given with user created content.
* SeldomSeenSpecies: Everywhere. Japanese Serow, Bowhead Whales, Olive Baboons, ''Camptosaurus'', Markhor, Blackbuck, ''Caudipteryx''...
** Continues in the second game with False Killer Whales, Pygmy Hippos, Geladas, Ethiopian Wolves, Goblin Sharks, ''Metridiochoerus''...
* ShoutOut: In the first game, placing a lion, tiger, and bear in a single exhibit will unlock a [[Film/TheWizardOfOz yellow brick pathway.]]
* ShownTheirWork:
** While not done entirely accurately, the ''Velociraptor'' in "Extinct Animals" has feathers.
** Many of the pterosaur fan-mods launch quadrupedally.
** The game shows giraffes walking correctly. Giraffes walk by moving both right legs at the same time, then both left legs at the same time.
* SpiritualSuccessor: ''World of Zoo'', another Blue Fang production, can be seen as this.
* StockDinosaurs: Played straight and averted, fan-favorites like ''[[TyrannosaurusRex T. rex]]'', ''Triceratops'' and ''Stegosaurus'' can be adopted but so can obscure creatures like ''Sivatherium'', ''Stokesosaurus'' and ''Protarchaeopteryx''.
* TakeThat: If guests don't like your zoo and begin to leave, they'll mention going to an [[VideoGame/RollerCoasterTycoon amusement park]] instead.
* TyrannosaurusRex
* {{Unicorn}}: Can be unlocked in the first game by naming a exhibit "Film/{{Xanadu}}". Interestingly, the males are black and orange and the females white. They also sound exactly like the zebras in the game. You could chalk it up to lazy programming, but they bothered to give the wild horses proper neighs...
* VideoGameCrueltyPotential:
** To both the animals and the guests. It's possible to sic lions and other predators on your prey animals or guests. There is even a nice animation for the ''T. rex'' when it attacks a man. It tosses him into the air and swallows him alive.
** You can also pick up your guests and put them in a tank, where they will drown if you block the way out.
** You pretty much can treat your animals as good or bad as you like, though the game does punish you if you are mean to them.
** VideoGameCrueltyPunishment: Having too many unhappy animals will make you unable to adopt new ones. The only way to lift this restriction is raising the existing animals' happiness to higher levels.
* VideoGameCaringPotential: If you like animals, you'll probably fulfill the Caring Potential more than the [[VideoGameCrueltyPotential Cruelty Potential]]. Even if you ''do'' occasionally let your Komodo dragons out when guests are being annoying.
* VideoGameTime: Days and months will pass in-game while your guests walk from one end of the zoo to another.
* WallCrawl: Graphics limitations can result in [=ZT2=] animals walking on near-vertical cliff walls as if they're horizontal.
* WouldntHurtAChild / WouldntHitAGirl: Your predators will never hurt women or children no matter how hungry they are. They will attack men, however.
* YouAreNumberSix: The default name of the animals are basically "[Species Name] [Number]". For example: Nile Crocodile 1, or Polar Bear 4.
