Giovanni Battista Doni (bap. 13 March 1595 – 1 December 1647) was an Italian music theorist, classicist and philologist who made an extensive study of ancient Greek music. He is known, among other works, for having renamed the note "Ut" to "Do" in solfège.

In his day, he was a well-known lawyer, classical scholar, critic and musical theorist, and from 1640 to 1647 he occupied the Chair of Eloquence at the University of Florence and was a prominent member of the city's Accademia della Crusca, the premier academic philologic society of Florence and Italy at the time. They had published the first Italian-language dictionary and grammar in 1612.
