Cows are a recurring race in the Legend of Zelda series that roam Hyrule and its surrounding countries. They are generally docile, and often domesticated to be kept as livestock in farms such as Lon Lon Ranch. Although their most frequent vocalization is a sound similar to "moo", in The Legend of Zelda: Ocarina of Time and Majora's Mask they do possess the ability to speak in a language Link can understand. In The Legend of Zelda: The Minish Cap Link can only understand their language when in Minish form.
- "Cows from Lon Lon Ranch had a reputation in Hyrule for providing the best tasting milk. In addition to quenching thirst, the milk was rumored to possess special powers."
- — Nintendo Power Player's Guide description
At Lon Lon Ranch, Link can enter a hurdle race with Epona. If he beats the 50-second record, Malon will reward him by sending a cow to his house. Cows are also found in hidden Hidden Holes throughout Hyrule. Cows are the source of milk, which contain nutritious healing properties. If "Epona's Song" is played within earshot of a cow, it will thank Link for the song and provide him with milk, if he has a bottle to keep it in.
In the Master Quest versions, cows can be seen Inside Jabu-Jabu's Belly, protruding from the walls and ceiling, without explanation, though possibly eaten as food. When hit with the Fairy Slingshot or Boomerang they can sometimes trigger events similar to a switch. These cows can still give Link milk when he plays "Epona's Song" near them. This does not work with the cow located in the water.
Cows can be found at Romani Ranch. If Link goes to Romani Ranch during the First Day, Romani will tell him a story of how mysterious creatures, possibly aliens, come to Romani Ranch once a year to steal their cows. Link can aid her by fighting off the creatures during nighttime. If he successfully manages to stop the creatures from reaching the barn, he is given a bottle of Milk. Additionally Romani's Mask is based on a cows head and the Milk Bar has a cow theme (such as its cow print bar).
There are also ten cow bobbleheads that can be found throughout Clock Town. Their heads will bobble more as the ground starts to shake on the Final Day or as Link performs a somersault and hits a wall near them. They serve no purpose to the story, but the Keaton asks Link how many there are in Clock Town during the Keaton Quiz.
There are five more cows in the game. Two are located in a Hidden Hole underneath the hollow log south of Clock Town. Two more are hidden in a hole on the Great Bay Coast cliff. The other is located, bizarrely, Beneath the Well.
In the 3DS remake, Cows are revealed to be the favorite prey of the Mooranha a brutal species of piranha native to Termina that lives in the Swamp Fishing Hole. Due to their reputation for attacking Cows they have been dubbed the Swampland Cow Killer and they cannot resist the sight of a cow as it drives them into a feeding frenzy. Link is able to use its trait of targeting cows to his advantage by wearing Romani's Mask (which is based on a cow) allowing Link to catch one using the Fishing Rod.
Like in Ocarina of Time, Link can receive a helping of Milk if he plays Epona's Song near a cow and has an empty bottle.
A breed of cow called Hateno Cows appear in villages such as Hateno Village and Lurelin Village. Unlike cows seen in past games, Hateno Cows cannot speak and Link cannot obtain milk from them directly. The description for Fresh Milk explains that it comes from Hateno Cows and white goats raised in Hateno Village, although the milk bottles only depict a cow. Link can feed cows with Hyrule Herbs but it serves no purpose. If Link attacks them, they will run away and not attack him. Link can add the Hateno Cow to the Hyrule Compendium by taking its picture with the Camera Rune.
Cows appear as enemies in Freshly-Picked Tingle's Rosy Rupeeland.
