\"I Want to Know What Love Is\" is a power ballad by the British-American rock band Foreigner. It was released in November 1984 as the lead single from their fifth album, Agent Provocateur. The song hit number one in both the United Kingdom and the United States and is the group's biggest hit to date. It remains one of the band's best-known songs and most enduring radio hits, charting in the top 25 in 2000, 2001, and 2002 on the Billboard Hot Adult Contemporary Recurrents chart. \"I Want to Know What Love Is\" has continued to garner critical acclaim, and is listed as one of Rolling Stone Magazine's greatest songs of all time at number 479. The song is also featured in a number of films.
\"I Want to Know What Love Is\" reached number one in the UK Singles Chart on January 15, 1985, displacing Band Aid's \"Do They Know It's Christmas?\", staying there for three weeks, and knocked Madonna's long-running \"Like a Virgin\" out of number one on the Billboard Hot 100 on February 2, 1985. It was Foreigner's first and only pop chart topper in either country, although the band had four number one Mainstream Rock hits and a number one Adult Contemporary radio hit in the US. This was the band's third of four number one singles on the Mainstream Rock chart. The song spent five weeks at number one in Australia and also hit the top of the charts in Canada, Ireland, New Zealand, Norway, and Sweden, peaking at number two in Switzerland and South Africa.
