Winfield Scott "Scotty" Moore III (born December 27, 1931 near Gadsden, Tennessee) is an American guitarist. He is best known for his backing of Elvis Presley in the first part of his career, between 1954 and the beginning of Elvis' Hollywood years. He was ranked forty-fourth in Rolling Stone magazine's list of 100 Greatest Guitarists of All Time.

Scotty Moore learned to play the guitar from family and friends at eight years of age. Although underaged when he enlisted, Moore served in the United States Navy between 1948 and 1952.

Moore's early background was in jazz and country music. A fan of guitarist Chet Atkins, Moore led a group called the "Starlite Wranglers" before Sam Phillips at Sun Records put him together with then teenage Elvis Presley. Phillips believed that Moore's lead guitar and double bassist Bill Black was all that was needed to augment Presley's rhythm guitar and lead vocals on their recordings. In 1954 Moore and Black accompanied Elvis on what was going to be the first legendary Presley hit, the Sun Studios session cut of "That's All Right (Mama)", a recording regarded as a seminal event in rock and roll history. Elvis, Black and Scotty Moore then formed the "Blue Moon Boys". They were later joined by drummer D.J. Fontana. Beginning in July 1954, the "Blue Moon Boys" toured and recorded throughout the American South and as Presley's popularity rose, they toured the United States and made appearances in various Presley television shows and motion pictures.
