"Walking on Sunshine" is a song written by Kimberley Rew for British rock band Katrina and the Waves' 1983 eponymous debut full-length album.

It was the Waves' first American top 40 hit, and their biggest success in the UK until "Love Shine a Light" (1997), which won them the Eurovision Song Contest 1997 held in Dublin.

Lead singer Katrina Leskanich thought "it wasn't really us", while bassist Vince de la Cruz found it irritating.
