Carmine Ugo Mariano was an American jazz saxophonist who focused on the alto and soprano saxophone. He occasionally performed and recorded on flute and nadaswaram as well.

The soprano saxophone is a higher-register variety of the saxophone, a woodwind instrument invented in the 1840s. The soprano is the third-smallest member of the saxophone family, which consists of the sopranissimo, sopranino, soprano, alto, tenor, baritone, bass, contrabass saxophone. Soprano saxophones are the smallest and thus highest-pitched saxophone in common use.
