The Free Zone (or independent Scientologists or Scientology Freezone) comprises a variety of groups and individuals who practice Scientology-like beliefs and techniques independently of the Church of Scientology (CoS) . Such practitioners range from those who closely adhere to the original teachings of Scientology's founder L. Ron Hubbard, to those who have so far adapted their practices to be almost unrecognizable as Scientology. The term Free Zone was originally only used by a single organization, but the term is now commonly applied to all non-CoS Scientologists, although many dispute the application of the term to themselves. However, the group whose name became adopted as a generic term for independent Scientology was not the first independent Scientologist group; the blank">California Association of Dianetic Auditors, the oldest breakaway group still in existence, Additional convenience link at http://www.cs.cmu.edu/~dst/Library/Shelf/la90/la90-6e.html. claims a founding date of December 1950, predating the Church of Scientology itself.

A November 2004 press release published by the International Freezone Association cited what it says was a command written by _L. Ron Hubbard himself: "... before you go, whisper this to your sons and their sons: 'THE WORK WAS FREE. KEEP IT SO.'" (capitals as in press release).

Skeptic Magazine described the Free Zone as: "..a group founded by ex-Scientologists to promote L. Ron Hubbard's ideas independent of the Church of Scientology." A Miami Herald article wrote that ex-Scientologists joined the Free Zone because they felt that Church of Scientology leadership had: "..strayed from Hubbard's original teachings."
