The Process Church of the Final Judgement, also known as the Process Church, was a British religious group established in 1966 and disestablished in the 1970s. Its founders were the British couple Mary Ann MacLean and Robert de Grimston, who spread the group's practices across parts of the United Kingdom and United States in the late 1960s and early 1970s. The Process Church's beliefs have been described as "a kind of neo-Gnostic theology".
