Alex Hyde (February 17, 1898 – July 7, 1956) was an Americanjazz bandleader and violinist.
Hyde was born in Hamburg but his family emigrated to the U.S. when he was two. He founded his own dance band, the Romance of Rhythm Orchestra, and played with them locally in New York (1919–22) and throughout North America (1922–23). They first recorded in 1923, and when touring Germany in 1924, they released material on Deutsche Grammophon. Among Hyde's soloists for these recordings are Howard McFarlane, pianist Walker O'Neill, and saxophonist Eddie Grosso. He recorded as a leader with a different band in 1924-25, also in Germany; Gene Sedric plays on some of these recordings.
