Billy Wallace (March 26, 1917 – June 3, 1978) was an influential American country and rockabilly singer, songwriter, and guitarist. Known for his distinctive voice and unique guitar style, Wallace made a significant impact on the rockabilly genre. Born in Oklahoma City, Oklahoma, Wallace's family relocated to Athens, Alabama, where he grew up on his father's farm and developed his musical talents. Influenced by country music stars such as the Delmore Brothers, Rex Griffin, and Roy Acuff, Wallace began writing songs as a teenager.

In 1943, Wallace married and moved to Huntsville, Alabama, marking the beginning of his songwriting career when Bill Carlisle recorded one of his songs. Seeking greater opportunities, Wallace and his wife moved to Nashville, Tennessee. He recorded his first singles in 1950-51 for a small Tennessee record label, including tracks like "Southwind" and "I'm Gonna Turn You A'Loose." Although these early records did not chart, Wallace's songwriting gained traction when Webb Pierce's cover of his song "Back Street Affair" reached #1 on the country charts.

Wallace's songwriting success continued with compositions for notable artists such as Red Foley, Kitty Wells, and Patsy Cline. In 1956, he recorded with the Bama Drifters for Mercury Records, producing four songs that later became favorites among rockabilly enthusiasts. Unfortunately, Wallace suffered a stroke during his time at Mercury, which paralyzed his left side and temporarily halted his guitar playing. Despite this setback, he persevered, relearning to play guitar and continuing to record for various small labels throughout his career.

Though Wallace never achieved widespread fame, his contributions to country and rockabilly music, both as a performer and songwriter, left a lasting legacy.
