"4 Minutes" is a song by American singer and songwriter Madonna from her eleventh studio album Hard Candy (2008), featuring vocals by American singers Justin Timberlake and Timbaland. It was released as the lead single from the album on March 17, 2008, by Warner Bros. Records. According to Madonna, the song is about saving the environment and "hav[ing] a good time while we are doing it". She also cited the song as the inspiration for the documentary I Am Because We Are (2008).

The song was recorded at Sarm West Studios, in London, while the mixing of the track was finished at The Hit Factory studio, in New York City. Sound engineer Demo Castellon first worked on the vocals and then on the beats, while the synths were composed by Timbaland and Danja. An uptempo dance-pop song with an urban and hip hop style, "4 Minutes" incorporates Timbaland's characteristic bhangra beats and the instrumentation used in the song includes brass, foghorns and cowbells. The song's lyrics carry a message of social awareness, inspired by Madonna's visit to Africa and the human suffering she witnessed in the continent.

"4 Minutes" received positive reviews from critics, who called it a busy dance track and complimented its music, which was compared to that of a marching band. Some reviewers noted that it was Madonna who appeared more of a featured artist on the track, rather than Timberlake. The song peaked at number three on the US Billboard Hot 100, giving Madonna her 37th top-ten single, breaking the record previously held by Elvis Presley, as the artist with most top-ten hits. It remains Madonna's best-selling digital single in the United States, with sales of over three million copies. Internationally, "4 Minutes" topped the chart in 21 countries, including Australia, Canada, Germany, Italy, Spain and the United Kingdom.
