Sonny Thompson (probably August 23, 1916 – August 11, 1989), born Alfonso Thompson or Hezzie Tompson, was an American R&B bandleader and pianist, popular in the 1940s and 1950s.

There is some uncertainty over Thompson’s origins, as well as his birth name. Researchers Bob Eagle and Eric LeBlanc indicate that he was born in 1916 in Wilkinson County, Mississippi, but other sources state that he was born in 1923, either in Mississippi or in Chicago.
