Defying Gravity is the Act One finale of the Broadway musical Wicked, which opened in 2003 with music and lyrics by Stephen Schwartz. Originally performed by Idina Menzel as Elphaba, the song became the show's signature anthem of defiance and independence. It returned to mainstream attention with the 2024 film adaptation, where Cynthia Erivo performs it, spawning countless memes, parodies and reaction edits online. The short belted excerpt is now shorthand for a dramatic, liberating moment.
