"She Ain't You" is a song by American recording artist Chris Brown. The mid-tempo R&B, pop-flavored ballad was written by Brown, Jean Baptiste, Ryan Buendia, Kevin McCall and Jason Boyd, and was produced by Free School. It was sent to urban contemporary radio in the United States on March 28, 2011, as the fourth US single from Brown's fourth studio album, F.A.M.E. (2011). Musically, "She Ain't You" samples the remixed version of SWV's "Right Here" (1993), which in turn samples Michael Jackson's "Human Nature" (1983). The song's lyrics are about Brown falling in and out of love. "She Ain't You" received mixed to positive reviews from music critics.

"She Ain't You" reached number five on the US Hot R&B/Hip-Hop Songs chart, number 17 on the US Pop Songs chart, and number 27 on the US Billboard Hot 100 chart. Although it was only officially released in the US, the song also charted in Australia, Canada, New Zealand, Slovakia and the United Kingdom. The accompanying music video was directed by Colin Tilley and features Brown paying tribute to Michael Jackson. Brown performed "She Ain't You" at the 2011 BET Awards, on Today, and during his F.A.M.E. Tour.
