Joseph-Hector Fiocco (20 January 1703 – 21 June 1741), born in Brussels, was a composer and harpsichordist of the late Baroque period.

Joseph Hector Fiocco worked under his stepbrother's direction at the Ducal Chapel of the Notre-Dame du Sablon most sources cite some time before 1730.

In 1730, Joseph Hector became sous-maitre (submaster) of the Notre-Dame du Sablon; he did not keep this position for long, because he resigned in 1731 to become sangmeester (choirmaster) at Antwerp Cathedral.

[1] In connection with his cathedral employment, Fiocco wrote many choral works, including motets and Mass settings.

The first suite begins in the style of Couperin and ends with four Italian-style movements: Adagio, Allegro, Andante, and Vivace.
