The Secret Jewel Box is a ten-CD box set, a collection of music by guitarist Steve Vai, released in 2001.

Vai's website describes it as "not a compilation of Vai's catalog, but rather something far more conceptual.

The series includes soundtracks, rarities, outtakes and oddities, out of print albums, Vai’s recordings with Frank Zappa and with early bands Alcatrazz and The Classified, acoustic piano interpretations of Vai songs, even an eclectic audio art project.

Those who purchased the box were to be notified when the remaining CDs were ready.

The 100-page booklet was to be sent out to those who had collected all 10 CDs after the last CD was produced.
