"Stronger" is a song by American rapper Kanye West, released as the second single from his third studio album, Graduation (2007). The production was handled by West, with an extended outro co-produced with Mike Dean. The composition is electronic in nature, employing synthesizers as its prominent instrument. For the track, West utilizes a vocoder-affected vocal sample of "Harder, Better, Faster, Stronger" by French house duo Daft Punk. On "Stronger," West speaks about the resolve that comes when one is faced with adversity, with lyrics at the song's refrain that paraphrase Friedrich Nietzsche's famous dictum, "What does not kill him, makes him stronger." West also describes "Stronger" as an "emancipation", using the track to vent his frustration over mistakes he made in the past year.

The song's production process was arduous, with West and his team mixing the track reportedly over 75 times, including after its release as a single. Although he worked with eight different audio engineers and eleven different mix engineers around the world for the track, West still felt dissatisfied with the results and decided to enlist the aid of record producer Timbaland in redoing its drum programming prior to the release of Graduation. West felt "Stronger" paled in comparison to the sampled original, but Daft Punk were delighted by the song, leading to future collaborations. The single's music video was directed by Hype Williams, features sci-fi imagery based on the 1988 anime film Akira, and was shot largely in Tokyo, Japan. Kanye West's use of shutter shades in the music video became a signature of his in the late 2000s.
