Joseph-Hector Fiocco (20 January 1703 – 21 June 1741), born in Brussels, was a Belgian composer and violinist of the late Baroque period. His father, the Italian composer Pietro Antonio Fiocco, and one his older brothers (he had no fewer than 15 siblings, including the composer and choirmaster Jean-Joseph) were responsible for his musical education. Joseph-Hector also learned Greek and Latin well enough to be able to become a schoolteacher in both those subjects.
