"(Everything I Do) I Do It for You" is a song by Canadian singer-songwriter Bryan Adams. Written by Adams, Michael Kamen, and Robert John "Mutt" Lange, the power ballad was the lead single for both the soundtrack album from the 1991 film Robin Hood: Prince of Thieves and Adams's sixth studio album, Waking Up the Neighbours (1991). The single was released on June 17, 1991.

The song was an enormous chart success internationally, reaching the number-one position on the music charts of at least nineteen countries, notable exceptions in the Western World being Italy (number three) and Spain (number four). It is particularly notable for its success in the United Kingdom, where it spent sixteen consecutive weeks at number one on the UK Singles Chart, the longest uninterrupted run ever on that chart as of 2023. It also topped the Europe-wide sales chart for eighteen continuous weeks. In the United States, it topped the Billboard Hot 100, which combines radio airplay and sales, for seven weeks, but stayed at number one for seventeen consecutive weeks on the sales-only chart. It went on to sell more than 15 million copies worldwide, making it Adams's most successful song, and one of the best-selling singles of all time. The song has been covered by hundreds of singers and artists around the world.
