Over the Rainbow is a British television talent series that aired on BBC One from 26 March to 22 May 2010. It documented the search for a new, undiscovered musical theatre performer to play the role of Dorothy Gale in Andrew Lloyd Webber's 2011 stage production of the 1939 film The Wizard of Oz and a dog to play Toto for a one-off performance.

Produced by Talkback Thames for the BBC, the series was presented by Graham Norton. It followed previous collaborations between the BBC and Lloyd Webber to find new musical theatre performers: How Do You Solve a Problem Like Maria?, Any Dream Will Do and I'd Do Anything. The series was named after the song "Over the Rainbow" and was also aired by TV3 in Ireland.

Following a public telephone vote, 18-year-old Danielle Hope was crowned the winner of the series and was chosen to play Dorothy. Miniature Schnauzer Dangerous Dave was chosen to play Toto.

A Canadian version of the show aired on CBC Television in the autumn of 2012.
