Spanish Castle Magic

"Spanish Castle Magic" is a song written by Jimi Hendrix and performed by the Jimi Hendrix Experience. Produced by Chas Chandler, it is the third track from the album Axis: Bold as Love. The lyrics refer to a club near Seattle, where Hendrix sometimes played early in his career. The song was a staple of live shows and several live recordings were released after Hendrix's death.

The lyrics were inspired by Hendrix's high school years (roughly 1958–1961), when he regularly visited a roadhouse called "The Spanish Castle". The club was situated to the south of Seattle in what was then unincorporated King County (now the city of Des Moines, Washington). It was built in the 1930s to avoid Seattle's then restrictive nightclub laws. By 1959, the club began featuring top local rock groups such as The Fabulous Wailers and occasional touring stars. Events were hosted by Pat O'Day, Seattle's best known disc jockey of the era.

The song features Noel Redding playing an eight string Hagstrom bass routed through an Octavia effects unit, which Hendrix later overdubbed using the same bass. Hendrix also overdubbed some jazz chords on the piano, which he had heard sound engineer Eddie Kramer playing. AllMusic's Matthew Greenwald calls the progression "proto heavy metal" and compares it to the earlier Experience song, "Foxy Lady".

"Spanish Castle Magic" is one of the few songs from Axis: Bold as Love that Hendrix regularly performed in concert. Live recordings of the song are found on BBC Sessions, Live at the Oakland Coliseum, Stages, Live in Ottawa, Live at Woodstock, Blue Wild Angel: Live at the Isle of Wight, Winterland, and The Jimi Hendrix Experience box set.
