Fiorenzo di Lorenzo (c. 1440 – 1522) was an Italian painter, of the Umbrian school. He lived and worked at Perugia, where most of his authentic works are still preserved in the Galleria Nazionale dell'Umbria.
Fiorenzo is known from a few signed works, including the Madonna of the Recommended (1476) and a niche with lunette, two wings and predella (1487), as well as from the documentary evidence that he was decemvir of that city in 1472, in which year he entered into a contract to paint an altarpiece for the church of Santa Maria Nuova, the pentatych of the Madonna and Saints.
