"Every Breath You Take" is a song by the English rock band the Police from their fifth and final studio album Synchronicity (1983). Written by Sting, the single was the biggest American and Canadian hit of 1983, topping the Billboard Hot 100 singles chart for eight weeks (the band's only No. 1 hit on that chart), and the Canadian RPM chart for two weeks. Their fifth UK No. 1, "Every Breath You Take" topped the UK singles chart for four weeks. It also reached the top 10 in numerous other countries. In May 2019, the song was recognised by BMI as being the most played song in radio history.
"Every Breath You Take" is the Police's and Sting's signature song, and in 2010, it was estimated to generate between a quarter and a third of Sting's music publishing income.
