"Speed Demon" is a song by American singer and recording artist Michael Jackson from his seventh studio album, Bad.

Davitt Sigerson of Rolling Stone stated that the "filler" content in Bad—including songs such as "Speed Demon", "Dirty Diana" and "Liberian Girl"—made Bad "richer, sexier, and better than Thriller's forgettables".

[4] Sigerson described "Speed Demon" as being "the car song"..."a fun little power tale in which Jackson's superego gives his id a ticket".

[4] On the other hand, Stephen Thomas Erlewine of AllMusic commented that the "near-fatal dead spot[s] on the record" of "Speed Demon" and "Another Part of Me" represented "a sequence that's utterly faceless, lacking memorable hooks and melodies".

[7] Jay Cocks of Time noted that Jackson did great "vocal stunts" on Bad's tracks; such as "Speed Demon" and "Dirty Diana" and described the two songs as "nimble and fanciful as any of his dance steps".

[8] In his Bad 25 review, BBC Music's Mike Diver wrote that "Speed Demon" was "fun funk-rock that'd sit happily on a Prince album of the period, compositionally if not lyrically.

[13] As the video begins, Jackson tries to evade overzealous fans and interviewers (including the Noid from Domino's Pizza commercials), disguising himself as a rabbit named Spike.

In his review of Moonwalker, Dennis Hunt of The Los Angeles Times commented that the video (along with those for "Bad" and "Leave Me Alone") was "slick, well-crafted and expensive-looking."
