Nicolao Dorati (c. 1513 – February 1593) was an Italian composer and trombone player of the Renaissance, active in Lucca.
Nicolao was hired as a trombonist by the city when it created the Cappella di Palazzo in 1543, and in 1557 he became director of that ensemble, a position he kept for the rest of his life.
In addition to this considerable output of secular music, he wrote at least three motets, two of which were for six voices and published in 1585, and one of which survives incomplete.
One of his madrigals, a setting of the several stanzas of Ariosto's romantic epic Orlando Furioso describing the charms of the sorceress Alcina, appears in a collection by Cipriano de Rore, indicating the esteem in which the composer was held, either by Rore or his Venetian publisher.
These same stanzas were set by numerous other composers of the same era, including a young Orlande de Lassus.
