Once Upon a Time is an American fantasy drama television series that premiered on October 23, 2011, on ABC. The show follows various fairy-tale characters who were transported to the real world and robbed of their original memories by a powerful curse. The first six seasons were set in the fictitious seaside town of Storybrooke, Maine, with Emma Swan as the lead character, while the seventh takes place in a Seattle, Washington neighborhood called Hyperion Heights, with a new main narrative led by an adult Henry Mills.

It borrows elements and characters from the Disney franchise and popular Western literature, folklore, and fairy tales. Once Upon a Time was created by Lost and Tron: Legacy writers Edward Kitsis and Adam Horowitz. For the first six seasons, the series aired on Sundays at 8:00 pm ET/7:00 pm CT. On May 11, 2017, ABC renewed the series for a 22-episode seventh season, moving to Friday 8:00 pm ET/7:00 pm CT, which premiered on October 6, 2017.

A spin-off series, Once Upon a Time in Wonderland, consisting of 13 episodes, premiered on October 10, 2013, and concluded on April 3, 2014. It followed the journey of Alice, from Alice in Wonderland.

For the first six seasons, the series originally took place in the fictional seaside town of Storybrooke, Maine, in which the residents are actually characters from various fairy tales and other stories that were transported to the real world town and robbed of their original memories by the Evil Queen Regina (Lana Parrilla) who used a powerful curse obtained from Rumpelstiltskin (Robert Carlyle). The residents of Storybrooke, where Regina is mayor, have lived an unchanging existence for 28 years, unaware of their own lack of aging. The town's only hope lies with a bail-bonds person named Emma Swan (Jennifer Morrison), the daughter of Snow White (Ginnifer Goodwin) and Prince Charming (Josh Dallas), who was transported from the Enchanted Forest to the real world via a magic tree as an infant before she could be cursed. As such, she is the only person who can break the curse and restore the characters' lost memories. She is aided by her son, Henry (Jared S. Gilmore), with whom she was recently reunited after giving him up for adoption upon his birth, and his Once Upon a Time book of fairy tales that holds the key to breaking the curse. Henry is also the adopted son of Regina, providing a source of both conflict and common interest between the two women.
