Jean-Marie Villot (October 11, 1905 – March 9, 1979) was a French Cardinal of the Roman Catholic Church who served as Archbishop of Lyon from 1965 to 1967, Prefect of the Congregation for Council from 1967 to 1969, Vatican Secretary of State from 1969 to 1979, and Camerlengo from 1970 to 1979. He was elevated to the cardinalate in 1965.
Villot participated as a cardinal elector in both the August and October conclaves of 1978, which selected John Paul I and John Paul II respectively. In his capacity of Camerlengo, he served as the interim administrator of the Vatican between Paul VI's death and John Paul I's election, and between John Paul I's death and John Paul II's election.
