"Stronger" is a song by American hip hop artist Kanye West, released as the second single from his third studio album Graduation. It was produced by West and contains an extended outro co-produced with Mike Dean. The song contains a vocal sample of "Harder, Better, Faster, Stronger" byFrench house duo Daft Punk, who received songwriting credit and had their costumes appear in its accompanying music video. The single was first released digitally on July 31, 2007 and soon became West's third number-one single. It won a Grammy Award for Best Rap Solo Performance at the 50th Grammy Awards. As of June 2011, it has sold over 4,402,000 digital copies in the United States.

"Stronger" entered the Billboard Hot 100 on the charting week of August 11, 2007 at number forty-seven, the highest debut single on the chart that week. Over the next eight weeks, the song steadily climbed upwards, reaching the number one position on the charting week of September 29, 2007, pushing the previous week's chart topper, Soulja Boy Tell 'Em's "Crank That (Soulja Boy)" into the number two position. However, the following week, "Crank That (Soulja Boy)" replaced "Stronger" atop the charts, making West's single reach its peak for only one week. As of June 2011, the single has sold over 4,402,000 digital copies in the US alone. The song debuted at number three in the United Kingdom and rose to become West's very first British number one single. Climbing on downloads alone, it surpassed the prior week's number one single, Robyn's "With Every Heartbeat". It has also topped the Canadian Hot 100, New Zealand, and the Turkish Singles charts. "Stronger" also spent 18 weeks on the German Singles Chart. The song ended 2007 as the 19th biggest-selling single in the United Kingdom of that year.

In 2011 Stronger appeared on the soundtrack for the movie The Hangover Part II and in the scene where the characters walk through the airport.

In 2011, West performed the song live at the Victoria's Secret Fashion Show, starting the intro with a tribute to his mother who had died before his scheduled performance four years before, saying: “In 2007, I was supposed to perform this song on this show and I lost my superhero – now she’s my super-angel.”
