Bernardo de Rossi[1] (8 January 1687 – 2 February 1775) was an Italian Dominican theologian and historian.

He made his religious profession with the Dominicans at Conegliano, 1704, after which he studied at Florence and Venice.

His sanctity and learning won for him a wide reputation, and his correspondence with the great men of his time fills nine volumes.

His works, written in elegant Latin, show a vast erudition and a mind at once critical and profound.

De Rossi also ranks high as a writer on historical, patristic, and liturgical subjects.
