"Under the Bridge" is a song by American rock band Red Hot Chili Peppers and the eleventh track on their fifth studio album, Blood Sugar Sex Magik (1991). Vocalist Anthony Kiedis wrote the lyrics while reflecting on loneliness and the struggles of being clean from drugs, and almost did not share it with the band. Released in March 1992 by Warner Bros. Records, "Under the Bridge" was praised by critics and fans for its emotional weight. The song was a commercial success and the band's highest-charting single, peaking at number two on the Billboard Hot 100, number one on the Cash Box Top 100 and certified platinum. It was also a success in other countries, mostly charting within the top 10. Gus Van Sant directed the song's music video, which was filmed in Los Angeles.
