John Cornelius "Johnny" Hodges was an American alto saxophonist, best known for solo work with Duke Ellington's big band. He played lead alto in the saxophone section for many years. Hodges was also featured on soprano saxophone, but refused to play soprano after 1946. Along with Benny Carter, Hodges is considered to be one of the definitive alto saxophone players of the big band era.

The alto saxophone is a member of the saxophone family of woodwind instruments. Saxophones were invented by Belgian instrument designer Adolphe Sax in the 1840s and patented in 1846. The alto saxophone is pitched in the key of E♭, smaller than the B♭ tenor but larger than the B♭ soprano. It is the most common saxophone and is used in popular music, concert bands, chamber music, solo repertoire, military bands, marching bands, pep bands, carnatic music, and jazz.
