"I See the Light" is a song written by composer Alan Menken and lyricist Glenn Slater for Walt Disney Animation Studios' animated film Tangled (2010). A duet originally recorded by American recording artist and actress Mandy Moore and American actor Zachary Levi in their respective film roles as main characters Rapunzel and Flynn Rider, the folk-inspired pop ballad serves as both the film's love and theme song. Lyrically, "I See the Light" describes the developing romantic relationship between Rapunzel and Flynn, and is featured as the seventh track on the film's soundtrack album.

Tangled is a 2010 American animated musical adventure fantasy comedy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. Loosely based on the German fairy tale "Rapunzel" in the collection of folktales published by the Brothers Grimm, the film was directed by Nathan Greno and Byron Howard, and produced by Roy Conli, from a screenplay written by Dan Fogelman. Featuring the voices of Mandy Moore, Zachary Levi, and Donna Murphy, Tangled tells the story of Rapunzel, a lost young princess with magical long blonde hair who yearns to leave her secluded tower. She accepts the aid of an intruder, the outlaw Flynn Rider, to take her out into the world which she has never seen.
