"A Life Less Ordinary" was a non-album single released by the band Ash on 13 October 1997. It was the title track of the film of the same name, A Life Less Ordinary, starring Cameron Diaz and Ewan McGregor, and also appeared on the film's soundtrack. The single was released in three formats: CD, 7-inch vinyl, and cassette. The limited-edition 7-inch was printed on blue vinyl. The song peaked at number ten on the UK Singles Chart.

Ash was personally requested by the director of the film, Danny Boyle. This was also the first song to feature their new guitarist, Charlotte Hatherley.

The song had the working title of "Film Song". Frontman Tim Wheeler had this to say about the lyrics: "This is a song about my muse. Robert Graves wrote a book called 'White Goddess' about the goddess of poetry, which is a concept that goes back to the ancient Greeks. Maybe this makes me sound completely mad, but I have this thing about music coming from a higher place. So, I was writing a song about the goddess. It's a weird love song. It says how I'd sell my soul for something to believe in, something more significant than everyday life."

The song was remixed in a slightly heavier fashion for the Japanese and US versions of Nu-Clear Sounds.
