Gherardello da Firenze (also Niccolò di Francesco or Ghirardellus de Florentia) (c. 1320–1325 – 1362 or 1363) was an Italian composer of the Trecento.
Later he became a priest, and then served as chaplain of Santa Reparata from 1345 until 1351—during the years that the Black Death ravaged the city.
A Gloria and an Agnus Dei, both by Gherardello, are among just a handful of mass movements by Italian composers from before 1400.
Most of Gherardello's music has been preserved in the 15th century Squarcialupi Codex, although several other manuscripts, all from Tuscany, contain works of his.
A portrait on the pages of the Codex devoted to his music is most likely him (each composer in that illuminated manuscript is pictured).
