Maurizio Galbaio (Latin: Mauricius Galba) (died 787) was the seventh traditional, but fifth historical, Doge of Venice from 764 to his death.

He is considered to be the first great doge, who reigned for 22 years and set Venice on its path to independence and success.

[1] Maurizio was raised to the dogeship at a time when two tribunes were being elected annually to check the power of the doge.

On the little island of Olivolo (now Castello), he reconsecrated the church of Saints Sergius and Bacchus as that of St Peter.

The low point of Maurizio's reign was the expulsion from the Pentapolis of Venetian traders for trading in slaves and eunuchs.
