"I Took a Pill in Ibiza" (also known by its censored title "In Ibiza" or its clean title "I Took a Plane to Ibiza") is a song by American singer Mike Posner. The song, originally acoustic guitar-based, was remixed by the Norwegian duo SeeB and released in the United States on July 24, 2015, digitally as a single from Posner's second EP, The Truth as well as the lead single from his second studio album, At Night, Alone..

The SeeB remix reached the top ten of the charts in twenty seven countries, including number one in Belgium, Ireland, Israel, Netherlands, Norway and the United Kingdom. In the latter country, the song remained at the top of the charts for four weeks. It has achieved high chart positions in Posner's native United States, where it reached number one on both the Billboard Dance/Mix Show Airplay Chart and the Billboard Pop Songs chart. It also peaked at number four on the main chart Billboard Hot 100. The song became Posner's biggest single, outperforming his debut, "Cooler than Me" (2010), and was later nominated for Grammy Award for Song of the Year.

It was sort of a mystery pill. I was already under the influence of alcohol at the time. I had written a song with Avicii that week in Sweden called “Stay with You” and he was playing in Ibiza so I said, ‘I will just go there with you,’ because I was already in Europe. I don’t have like a regular 9–5 job … so might as well go to Ibiza, right? I had never been there before. So I went. We were at his show and I was drinking at the time. I just sort of moseyed out into the audience to watch Avicii spin from their point of view. I would go back and forth between the backstage and the VIP area and then where the actual kids were. And most people didn't know who the fuck I was in Ibiza except for this one guy who recognized me. He was like, 'Are you Mike Posner?' and he was all excited. He holds up this little bag of pills and is like, 'You want one?' And drunk Mike Posner was like, 'Fuck it, yeah.' So I took one and I had never done that before, and then I felt amazing. Then when I came down I felt 10 years older.
