"I Was Gonna Cancel" is a song by Australian recording artist Kylie Minogue, released as the second and final single from her twelfth studio album Kiss Me Once. The track was written and produced by American recording artist, songwriter and producer Pharrell Williams who she met while in Los Angeles, California. It was released in the United Kingdom on 11 May 2014 and a day later in the United States.

Musically, the song is influenced by disco and funk, which noted similarities from William's previous work and Daft Punk. Lyrically, the song was based on Minogue's conception of having a bad day. "I Was Gonna Cancel" received positive reviews from music critics, many recognizing it as the more "interesting" song on the record and praised Williams' production.

Following the release of The Abbey Road Sessions (2012), Minogue split ways with her long-term manager, Terry Blamey and signed a new management deal with rapper Jay-Z's imprint Roc Nation. Following this new deal, Minogue continued work on her twelfth studio album throughout 2013, with reports emerging in February 2013 that Minogue had been working with singer-songwriter Sia Furler. In an interview with Billboard, Minogue expressed that she had an epiphany during her "Kylie 25" campaign in 2012, stating, "I felt like I needed a new landscape, and once you've got your feet on the ground you're raring to go. [...] So far the support has been great, and it's just another part of this amalgamation of 'new' that I had wished for and was struck by."

During the recording process of Kiss Me Once, Roc Nation contacted Pharrell Williams to co-produce with Minogue. Eventually, Minogue had met Williams in Los Angeles, California to produce music with her. According to Minogue, she revealed that she had two days to produce only two songs with Williams, these being "I Was Gonna Cancel" and "The Winners" and stated that the first day she met him she started crying due to an overwhelming day.
