"Axel F" is the electronic instrumental theme from the 1984 film Beverly Hills Cop performed by Harold Faltermeyer. It was an international number 1 hit in 1985.

The title comes from the main character's name, Axel Foley (played by Eddie Murphy), in the film. (It also happens to be in the key of F minor.)

Faltermeyer recorded the song using five instruments: a Roland Jupiter-8 provided the distinctive "supersaw" lead sound, a Moog modular synthesizer 15 provided the bass, a Roland JX-3P and Roland JX-8P provided brassy chord stabs, a Yamaha DX7 was used for tube bell or bell, bass 1/bass and marimba sounds and a LinnDrum was used for drum programming.

According to Faltermeyer, the initial reaction to his premiere presentation of the cues to the film's producers and director didn't result in an immediate approval; it wasn't until director Martin Brest voiced his approval that the producers showed enthusiasm.

In addition to the Beverly Hills Cop soundtrack, the song also appears on Faltermeyer's 1988 album Harold F. as a bonus track. Reportedly, Faltermeyer was against including it, but MCA insisted as it was his most recognizable track.

This version of the song reached number 2 on the UK Singles Chart and number 3 on the Billboard Hot 100 in the US. It also spent two weeks atop the American adult contemporary chart.

In 2005, Crazy Frog recorded the song, releasing it as "Axel F", though it was also known as the "Crazy Frog song". The novelty song is Crazy Frog's first and most internationally successful single. The cover was produced by Matthias Wagner and Andreas Dohmeyer, the two members of Off-cast Project, and Henning Reith and Reinhard "DJ Voodoo" Raith, two members of the German dance production team Bass Bumpers. Wolfgang Boss and Jamster! arranged the remix, and later marketed it as a ringtone.
