Mark C. "Marty" Rathbun (born 1957) is an American former Scientologist who served as a senior executive of the Church of Scientology. He last held the post of Inspector General of the Religious Technology Center (RTC), the organization that is responsible for the protection and enforcement of all Dianetics and Scientology copyrights and trademarks. As the inspector general, Rathbun led the RTC's international Inspector General Network, collectively responsible for internal maintenance and consistency of Scientology's practices and procedures in its organizations, and for ensuring perfect adherence to all Church policies as attributed to Scientology founder L.
