Mary Sue Hubbard (1931–2002) was the third wife of L. Ron Hubbard and a prominent figure in Scientology. She began her involvement in Dianetics in 1951, later marrying L. Ron Hubbard in 1952. She played a crucial role in establishing the Church of Scientology and managing its operations. Notably, she helped coin the term 'Scientology'. However, her leadership faced challenges, including indictment and imprisonment due to illegal actions taken by the Church's Guardian's Office. She was married to Hubbard until his death in 1986 and had four children with him.
