An "ex-Jehovah's Witness" is a term used to describe someone who was formerly a member of the religious group known as Jehovah's Witnesses but has since left the organization or chosen to disassociate themselves from it. Jehovah's Witnesses are members of a Christian denomination with unique beliefs and practices, and individuals who decide to leave the group may refer to themselves as "ex-Jehovah's Witnesses" to indicate their former affiliation with the organization.
