"Walking on Sunshine" is a song written by Kimberley Rew for British rock band Katrina and the Waves' 1983 eponymous debut full-length album.
The rerecorded version was at first released on the band's 1985 self-titled album as the album's second single and reached No. 4 in Australia, No. 9 in the United States and No. 8 in the United Kingdom.
"Walking on Sunshine" was written by the band's guitarist Kimberley Rew. "I'd love to say Walking on Sunshine relates to a significant event in my life, like walking out of my front door, seeing a comet and being inspired," he told The Guardian in 2015. "But it's just a piece of simple fun, an optimistic song, despite us not being outstandingly cheery people".
