Wild Bill Davis (November 24, 1918 – August 17, 1995) was the stage name of American jazz pianist, organist, and arranger William Strethen Davis. He is best known for his pioneering jazz electric organ recordings and for his tenure with the Tympany Five, the backing group for Louis Jordan. Prior to the emergence of Jimmy Smith in 1956, Davis (whom Smith had reportedly first seen playing organ in the 1930s) was the pacesetter among organists.

Davis was born in Glasgow, Missouri and grew up in Parsons, Kansas. He first learned music from his father who was a professional singer. He received further musical training at the Tuskegee Institute (now Tuskegee University) in Alabama, and at Wiley College in Marshall, Texas. In his early career he took inspiration from Fats Waller and Art Tatum.
