Johnny Henry Smith II (June 25, 1922 – June 11, 2013) was an American cool jazz and mainstream jazz guitarist. He wrote “Walk, Don’t Run” in 1954. In 1984, Smith was inducted into the Alabama Jazz Hall of Fame.

During the Great Depression, Smith’s family moved from Birmingham, Alabama, United States, where Smith was born, through several cities, ending up in Portland, Maine.

Smith taught himself to play guitar in pawnshops, which let him play in exchange for keeping the guitars in tune. At thirteen years of age he was teaching others to play the guitar. One of Smith’s students bought a new guitar and gave him his old guitar, which became the first guitar Smith owned.

Smith joined Uncle Lem and the Mountain Boys, a local hillbilly band that travelled around Maine, performing at dances, fairs, and similar venues. Smith earned four dollars a night. He dropped out of high school to accommodate this enterprise.

Having become increasingly interested in the jazz bands that he heard on the radio, Smith gradually moved away from country music towards playing more jazz. He left The Mountain Boys when he was eighteen years old to join a variety trio called the Airport Boys.
