Don Carlo Barberini was an Italian nobleman of the Barberini family, Duke of Monterotondo and brother of Maffeo Barberini who was elected to the papal throne as Pope Urban VIII.

Carlo Barberini was the son of Don Antonio Barberini and Camilla Barbadori. As their eldest son he became patriarch of the Barberini family.

In 1594 he married Costanza Magalotti, daughter of Don Vincenzo Magalotti and Donna Clarice Capponi and sister of Lorenzo Magalotti.

They had 6 children including Taddeo Barberini, Francesco Barberini and Antonio Barberini (Antonio the Younger). When Barberini's brother was elected to the papal throne as Pope Urban VIII, Francesco and Antonio were both elevated to Cardinal. Taddeo was given the title, Prince of Palestrina, later passed on to successive Barberini patriarchs.

Barberini himself did not escape his brother's famous nepotism; he was appointed Gonfalonier of the Church and Duke of Monterotondo; a comune the Barberini later bought.
