"Anything Could Happen" is a song by English singer and songwriter Ellie Goulding, released as the lead single from her second studio album, Halcyon (2012). Written and produced by Goulding and Jim Eliot of English electropop duo Kish Mauve, the song received positive reviews from music critics.

In the United States, the track peaked at number forty-seven on the Billboard Hot 100 and topped the Hot Dance Club Songs chart.

The accompanying music video was directed by Floria Sigismondi and filmed in Malibu, California. The video depicts Goulding and her on-screen boyfriend getting into a car accident. "Anything Could Happen" was used in the Beats by Dre's #ShowYourColor campaign commercial and in the trailer for the second season of the HBO series Girls. The song has been covered by the Script, fun. and Fifth Harmony.

Goulding appeared on Fearne Cotton's BBC Radio 1 show on 9 August 2012 for the premiere of the song. She told Cotton, "I've been with this song a long time and I've had to listen to it a lot to get it just how I wanted it."

During a behind-the-scenes featurette for the "Anything Could Happen" music video, Goulding told MTV News, "I suppose it's one of those songs where I sort of talk about bits of my childhood, but also about my friendship with this person, and, um, I suppose it's a song of realization [...] And it's called 'Anything Could Happen,' [so] I'm hoping it will make people go out and propose to their girlfriends or go on that holiday they never ended up doing. I hope it will provoke positivity, as opposed to make people really sad."
