William Franklin "Billy" Graham, Jr. (born November 7, 1918) is an American evangelical Christian evangelist, ordained as a Southern Baptist minister, who rose to celebrity status with national media backing of William Randolph Hearst and Henry Luce in 1949. His sermons were broadcast on radio and television, with some still re-broadcast today.

Graham is notable for having been a spiritual adviser to several United States Presidents; he was particularly close to Dwight D. Eisenhower and Richard M. Nixon. During the civil rights movement, he began to support integrated seating for his revivals and crusades; in 1957 he invited Rev. Martin Luther King, Jr. to jointly preach at a huge revival in New York City, where they appeared together at Madison Square Garden, and bailed the minister out of jail in the 1960s when he was arrested in demonstrations.

Having built an evangelical empire and organized huge events worldwide, Graham has personally preached the Gospel to more people than any other person in history. His institutions include a variety of media and publishing outlets. According to his staff, more than 3.2 million people have responded to the invitation at Billy Graham Crusades to accept Jesus Christ as their personal Savior. As of 2008, Graham's estimated lifetime audience, including radio and television broadcasts, topped 2.2 billion.
