Giselle is a fictional character from Disney's romantic comedy fantasy film Enchanted (2007) and its sequel, Disenchanted (2022). She is both portrayed and voiced by actress Amy Adams. The character first appears in Enchanted as a cheerful maiden from the animated kingdom of Andalasia, whose plans to marry its prince are threatened when an evil queen banishes her to New York City. While trapped there, she meets and charms a cynical divorce lawyer, which complicates her feelings for the Andalasian prince to whom she is already engaged.

Created by screenwriter Bill Kelly and director Kevin Lima, Giselle is both a parody of and homage to classic Disney princess characters, specifically borrowing inspiration from Snow White, Cinderella, Aurora, and Ariel. Adams was selected out of approximately 300 actresses who auditioned for the role. Although Lima had always wanted to cast an unknown performer as Giselle, Disney executives were initially hesitant to hire Adams due to her relative obscurity at the time. Giselle's animated sequences were supervised by veteran Disney animator James Baxter, who referenced live-action footage of Adams to ensure the character was a cohesive combination of Adams and the classic Disney princess aesthetic.

Adams' performance was lauded by film critics, who praised her comedic timing, singing, and commitment to the character. Adams was nominated for a Golden Globe Award for Best Actress – Motion Picture Comedy or Musical, and the role is credited with establishing her as a leading lady in Hollywood. Some publications credit Giselle with reviving Disney's princess films following a period of decline. Due to disagreements over compensating Adams for using her likeness, Disney canceled its initial plans to induct Giselle into the Disney Princess franchise.

Giselle (Amy Adams), a young woman from the animated kingdom of Andalasia, has long fantasized about marrying her true love. She quickly becomes engaged to Prince Edward (James Marsden), but their marriage plans are jeopardized by Edward's stepmother, Queen Narissa (Susan Sarandon). Viewing Giselle as a threat to her throne, Narissa pushes her down a wishing well, transporting her to contemporary Manhattan, New York City. Disoriented and homeless in an unfamiliar environment, Giselle meets Robert (Patrick Dempsey), a disillusioned divorce lawyer and single father to Morgan (Rachel Covey). Reluctantly, Robert allows Giselle to stay in their apartment, straining his relationship with his fiancé, Nancy (Idina Menzel). As Giselle explores New York, Edward pursues her, determined to bring her back to Andalasia. Meanwhile, Narissa's henchman, Nathaniel (Timothy Spall), plots to sabotage Edward's mission by poisoning Giselle.

Despite her devotion to Edward, Giselle begins to develop feelings for Robert, and Robert is softened by Giselle's optimism in return. Meanwhile, the real world begins to transform Giselle into a complex human being. When Edward finally locates Giselle, she pleads to spend their last night in New York attending a costume ball, during which Giselle shares a romantic dance with Robert. Their moment is interrupted by Narissa who, disguised as an old woman, offers Giselle a magic apple promising that it will erase all memories of her time in New York so she can move on with Edward. However, the apple poisons her and Giselle falls into a deep sleep. Edward and Nathaniel intervene before Narissa can drag Giselle away. Robert deduces the spell can only be broken by true love's kiss. When Edward's kiss fails to awaken her, he quickly realizes Giselle's true love must be Robert instead. With Edward and Nancy's blessing, Robert kisses Giselle and she is revived. Enraged, Narissa transforms herself into a dragon and kidnaps Robert, dangling him from the top of the Woolworth Building. Giselle pursues them and catches Robert as Narissa falls to her death. In the end, Giselle chooses to stay in New York with Robert and Morgan, and launches her own princess-themed clothing line called "Andalasia Fashions", while Edward returns to Andalasia with Nancy, where they marry each other.

In the sequel Disenchanted, set 10 years later, Giselle moves with Robert, her now-teenage stepdaughter Morgan (Gabriella Baldacchino), and their newborn daughter, Sophia, to the seemingly idyllic suburban town of Monroeville. Giselle hopes to achieve a more ideal life than what she has been experiencing in New York City since marrying Robert, but still struggles to adapt to her new environment, finding herself at odds with Morgan and the town's "queen bee", Malvina Monroe (Maya Rudolph). Desperate for change, Giselle uses Sophia's wishing wand to wish for a "fairytale life", but starts transforming into Morgan's wicked stepmother instead, essentially becoming the villain in her own fairy tale. Giselle discovers that her wish is draining all magic from Andalasia to turn Monroeville into a fairy tale. If not reversed by midnight, the transformation becomes permanent, resulting in the disappearance of Andalasia and its inhabitants, including Giselle. Using the last of her innocence before completely transforming, Giselle sends Morgan to Andalasia, where Nancy and Edward teach her to harness her memories of Giselle to restore her stepmother's true nature. Morgan's drawing breaks the spell's effects on Giselle, but Malvina captures Morgan and demands the wand in exchange for her release. Giselle complies, but as midnight approaches, she weakens and begins to disappear. However, Giselle reminds Morgan that she can use the wand's magic as the daughter of an Andalasian. Morgan wishes to be home with her mother, breaking the spell and bringing Giselle, Monroeville, and Andalasia back to life. Only Giselle and Morgan remember the events of the previous day, while everyone else believes it was just a dream.

In an original draft of the story, the film's heroine asks to be sent to the "real world" to escape unrequited advances from a Prince Charming-type character. When Disney acquired the original script for Enchanted, the film had been intended for a much older audience. Screenwriter Bill Kelly had written a scene in which Giselle is mistaken for a stripper upon arriving in New York's red-light district. She is hired for a bachelor party, whose attendees become angry with her once she refuses to strip, prompting Robert to cancel the party and rescue her. Executive producer Doug Short claims the bachelor party was not abandoned exclusively because of its mature tone, but rather the removal of Robert's friends naturally allowed the story to prioritize Giselle and Robert's relationship. By 2005, Disney commissioned Kelly to write a new draft that aligned with the studio's tradition of yearning heroines. Director Kevin Lima revised the script with Kelly to have Giselle arrive in Times Square, and the bachelor party was ultimately replaced with Giselle hanging from a castle-shaped billboard, where she meets Robert for the first time.

Short said the hardest part of developing Giselle as a character was establishing a balance between her comedic antics and relatability, without simply making her a "fool" or evolving her at the expense of her happy personality. Because she is a parody of and homage to classic Disney princess tropes, the filmmakers borrowed inspiration from several Disney princesses, with Lima describing Giselle as "80% Snow White" with traits of Cinderella and Aurora, combined with Ariel's spunk. Caroline Siede of The A.V. Club observed that the original three lend themselves more easily to parody as "the least progressive Disney princess films", whereas Ariel represents a transition towards more empowered heroines. Lima noted Giselle's distinguishing trait is that while her predecessors are largely reactive, Enchanted's contemporary setting forces Giselle to become an active participant in her own fairy tale and rely on her innate ability to adapt to new situations in order to survive unfamiliar circumstances. Kelly identified Giselle as his favorite character to write for.
