"Magic Stick" is a song by American rapper Lil' Kim featuring fellow American rapper 50 Cent, released on April 8, 2003 as the second single from her third studio album La Bella Mafia (2003). The song was produced by Carlos "Fantom of the Beat" Evans. Despite not having a physical release or music video, the song performed very well on the charts, peaking at number 2 on the Billboard Hot 100.

The song samples "It Be's That Way Sometimes" by Joe Simon. The song was originally intended for 50 Cent's album Get Rich or Die Tryin' and featured rapper Trina. After Trina sent her verse back to 50 Cent, he decided that she wasn't suited well for the song. 50 Cent then sent the song to Lil' Kim,^[1] who failed to send the song back to 50 Cent before the deadline for his record, so he let her use it for her album La Bella Mafia.^[2] A sequel to "Magic Stick", titled "Wanna Lick (Magic Stick, Pt. 2)", was recorded by the pair and released on Lil' Kim's 2008 mixtape Ms. G.O.A.T.

The song is featured in the films King's Ransom and Now You See Me 2, as well as the animated series The Cleveland Show, on the episode titled “Brown Magic”.

The song debuted on the Billboard Hot 100 on April 26, 2003 at number 75^[3] peaking at number two, kept out of the number one spot by "Crazy In Love" by Beyoncé ft. Jay-Z.^[4] A video was scheduled to be shot, but problems between Lil' Kim and 50 Cent caused the shoot to be canceled. The song received massive radio airplay, peaking at number one on the airplay chart, and it spent a total of 24 weeks on the Hot 100.^[5] The song charted as Kim's second-highest single (as a lead artist), and her second-highest overall, after 2001’s "Lady Marmalade" with Missy Elliott, Mya, P!nk, and Christina Aguilera. It also became 50 Cent's second overall top-10 and top-three single.

Lil' Kim performed the song in 2011 at the latter's show in Australia.^[6]
