Operation Freakout, also known as Operation PC Freakout, was a Church of Scientology covert plan intended to have the U.S. author and journalist Paulette Cooper imprisoned or committed to a psychiatric hospital. The plan, undertaken in 1976 following years of church-initiated lawsuits and covert harassment, was meant to eliminate the perceived threat that Cooper posed to the church and obtain revenge for her publication in 1971 of a highly critical book, The Scandal of Scientology. The Federal Bureau of Investigation discovered documentary evidence of the plot and the preceding campaign of harassment during an investigation into the Church of Scientology in 1977, eventually leading to the church compensating Cooper in an out-of-court settlement.

The Church of Scientology is a group of interconnected corporate entities and other organizations devoted to the practice, administration and dissemination of Scientology, which is variously defined as a cult, a business, or a new religious movement. The movement has been the subject of a number of controversies, and the Church of Scientology has been described by government inquiries, international parliamentary bodies, scholars, law lords, and numerous superior court judgements as both a dangerous cult and a manipulative profit-making business. In 1979, several executives of the organization were convicted and imprisoned for multiple offenses by a U.S. Federal Court. The Church of Scientology itself was convicted of fraud by a French court in 2009, a decision upheld by the supreme Court of Cassation in 2013. The German government classifies Scientology as an unconstitutional sect. In France, it has been classified as a dangerous cult. In some countries, it has attained legal recognition as a religion.
