Snow White, formerly known as Mary Margaret Blanchard in Storybrooke, is a fictional character in ABC's television series Once Upon a Time.

She is portrayed by Ginnifer Goodwin and by Bailee Madison as a child. She is the true love of Prince Charming/David Nolan, mother of Emma Swan and son Neal, and grandmother of Emma's son Henry. The character has been one of Goodwin's best roles, one she loves playing on the show.

Before accepting the role, Goodwin stated in interviews that she'd always wanted to play Snow White and called her acceptance of the role "a no-brainer.[5] Kitsis and Horowitz are self-described big fans of Goodwin's previous series, Big Love, and wrote the part of Snow with Goodwin in mind.
