Vincenzo Bellavere (also Bell'haver, Bell'aver, Belaver) (c.1540-1541 – 29 August 1587) was an Italian composer of the Venetian School.
In 1568 he acquired the position of primary organist at the Scuola Grande di San Rocco, a Venetian establishment almost as prestigious as St. Mark's; he held this post until 1584 at which time he returned to Padua to take the post at the cathedral that he at first failed to win.
In December 1585 he was fired from his job in Padua, probably because of an unexcused absence, but he returned to Venice to become organist of yet another Venetian church, Santo Stefano.
Bellavere was a talented composer and could have become a major member of the Venetian school, had his career not been cut short; possibly he died fairly young, though reliable information on his age is missing.
His last music shows a progressive use of the multiple choir and instrument group style that was to make Giovanni Gabrieli famous, and which is the hallmark of the Venetian School.
