Judy Z. Knight (born Judith Darlene Hampton, March 16, 1946 Roswell, New Mexico) is the CEO of JZK, Inc, of which one part is Ramtha's School of Enlightenment [ Knight claims that on 7 February 1977, an entity called Ramtha, The Enlightened One appeared to her and her husband in her kitchen in Tacoma, Washington.

He apparently trained her for out-of-body experiences, and since then she has been able to act as a medium, channeling this being. JZ Knight says that is how she is able to channel Ramtha by going through a process of leaving her body, through which he then teaches.

She appeared on The Merv Griffin Show in 1985, and later wrote an autobiography A State of Mind in 1987. Time called her at that time "probably the most celebrated of all current channellers."[1] Ramtha's School of Enlightenment Web site claims that since 1988, through the JZ Knight Humanities Foundation, that JZ has given $1,181,067.93 dollars to 200 graduating high-school seniors "that they may pursue their educational goals." In 1996, a total of $280,000.00 was given to 39 graduating seniors. Yelm High School counselor Carol Parker is quoted on the Web site: JZ has done a lot for the kids in our community.

Her generous scholarships have given them the opportunity to further their education."[2] Knight now lives in a French-chateau-styled mansion in the outskirts of Yelm, Washington, where she teaches courses nationally and internationally and runs Ramtha's School of Enlightenment, The Outback Boutique, and JZK Publishing – amongst other pursuits. In the early 1990s, Knight’s high-profile divorce case appeared in the tabloids: Ex-husband Jeffrey Knight accused her of blackmail and psychological bullying. Knight has been married five times, and has been with her current partner for ten years.

Although absent from public view for almost five years, she has returned to public speaking, on radio and in magazines and workshops.
