"Black Sweat" is a song by Prince that was released as the second single from his 2006 album 3121. The music video to accompany the single was released on February 2, 2006. At the 49th Annual Grammy Awards, it was nominated for Best R&B Song and Best Male R&B Vocal Performance.

The song showcases minimalist funk alongside hip hop elements. Similar to "When Doves Cry" and "Kiss", a bassline is absent from the mix, which is an unusual occurrence in a pop song. Essentially, the only instruments are drum machines and high-pitched synthesizers. Prince delivers most of the song in his trademark falsetto.

The video is as minimalist as the song itself, presented in black and white. It consists of just one scene of a blank background and a 1970s-styled chair placed in the center. The video stars Prince and features Celestina Aladekoba (a dancer featured heavily in Jennifer Lopez's TV reality show, DanceLife), who is dancing seductively to the music, occasionally leaning over the chair as Prince sings. In a nod to the "Kiss" video, Prince humorously makes a disgusted expression when Celestina screams "like a white lady" (which is actually the keyboard riff). The video was directed by Sanaa Hamri.

For the week ending March 11, 2006, "Black Sweat" debuted on the Billboard Hot 100 at number 60 (Prince's highest debut in years), and at number 83 on the Hot R&B/Hip-Hop Singles and Tracks chart. It also debuted at number one on Billboard's Hot 100 Singles Sales chart, which tabulates both physical and digital sales.
