Vinzenz Fux (Vincenzio Fuxio), (c.1606–1659) was an Austrian musician and composer.
Fux was born in Weißkirchen, Styria, and was employed as the organist of the church Maria am Gestade in Vienna before he joined the chapel of Eleonora Gonzaga, widow of Holy Roman Emperor Ferdinand II.
Fux mainly composed Masses and trio sonatas, which have survived in manuscripts.
It is testimony of their high quality that they were even taken at times for works of the later imperial chapelmaster Johann Joseph Fux, who was however not related to Vinzenz Fux.
Vinzenz Fux died in Vienna, in his early fifties.
