Arnold Johnson (March 23, 1893 in Chicago – July 15, 1975 in St. Petersburg, Florida) was an American big band pianist, arranger, composer, and leader during the swing jazz era. He was orchester leader on the popular The Majestic Theater of the Air program on the CBS radio network beginning in 1929. Johnson disbanded the group in the early 1930s, and became involved in the broadcasting business, working as a director and producer of radio programs such as National Amateur Night.
