Masada is a musical group with rotating personnel led by American saxophonist and composer John Zorn since the early 1990s.

Masada is as much a "songbook" as a group, comprising more than 500 relatively brief compositions. Each song is written in accordance with a number of rules, including the maximum number of staves, the modes or scales that are used, and the fact that the songs must be playable by any small group of instruments.
