Link is the name shared by the main protagonists of The Legend of Zelda series. There are many incarnations of Link, each possessing the Spirit of the Hero, with some of them being blood-related as well.They are chosen by the Goddesses to protect the land from evil whenever deemed necessary. They often need to complete a series of trials to mature into the chosen hero. In the majority of Zelda games, their adventures take place within Hyrule, traveling through the land, collecting important items, and defeating a wide variety of enemies while trying to save both Princess Zelda and her kingdom from the clutches of Ganon, Vaati, or other villains.

The first Link was introduced as a young Sword-wielding boy, but since The Adventure of Link, the identity, appearance, and role of each incarnation of Link has varied from game to game. Many of the Links are given titles to identify them, such as the Hero of Time in Ocarina of Time and the Hero of Winds in The Wind Waker.
