Rudolph Atwood (December 16, 1912 – October 16, 1992) was an American Christian music pianist, known primarily for his years as accompanist on the long-running Old Fashioned Revival Hour radio program led by Charles E. Fuller from 1937 to 1968 on the Mutual Broadcasting System and later on the ABC Radio Network. After Fuller's death in 1968, Atwood continued to play on the successor program, The Joyful Sound. He made many recordings accompanying the program's quartet and choir and made appearances playing the piano at various churches and concerts until his death in 1992. He was known as "the most imitated pianist in gospel music", for his improvisations and arrangements of traditional hymns.
