Link's Mother

Link's Mother is a character not yet shown in any Zelda video game, but alluded to in and shown in media based on the series, such as the manga and comics.

Ocarina of Time
Link's Mother is an unnamed woman who birthed and cared for Link before the events of. She is credited with protecting and entrusting baby Link with the Great Deku Tree in the Kokiri Forest during the time of the Hyrulean Civil War. Link knows nothing of his mother, let alone both parents, because his mother died shortly after giving him up to the Great Deku Tree. In presiding over the Kokiri race, The Great Deku Tree chose to raise Link as a Kokiri, despite his Hylian blood. Because of this, Link awakens in the beginning of Ocarina of Time wearing Kokiri garb, and in the presence of a fairy, a facet of Kokiri society that is prevalent in all of its members.

A mother figure is not mentioned in any other canonical game since Ocarina of Time, where the only mention of her existence is revealed to Link after he completes the Forest Temple, by the freshly-grown Deku Tree Sprout.

A Link to the Past comic
In the A Link to the Past comic, it is revealed that Link's parents were both Knights of Hyrule; however, they somehow stumbled into the Dark World, leading Link to be adopted by his uncle instead. When Link's Uncle is defeated by Agahnim, he mentions that if the young hero manages to rescue Princess Zelda and the people in the Dark World, he might be able to meet his parents.

Link's parents are seen for the first time in the comic as Link is walking through Death Mountain, where he activates one of the Dark World portals  and sees a vision of his mother and father. Although Link tries to  reach out for his mother's hand, his hand turns into a claw when it passes the   portal's boundary. Link's parents are not seen again until the final chapter after Link has defeated Ganon and peace returns to Hyrule. At Hyrule Castle,  Link sees a vision of his father, mother and uncle,  who congratulate   him on his difficult victory and tell him to never  forget  the efforts   of the many generations of knights and Wise Men  that  preceded him.
