Michelangelo Rossi (Michel Angelo del Violino) (ca. 1601/1602 – 1656) was an important Italian composer, violinist and organist of the Baroque era.
Rossi was born in Genoa, where he studied with his uncle, Lelio Rossi organist (from 1601 to 1638), at the Cathedral of San Lorenzo. Around the year 1624 he moved to Rome to enter the service of Cardinal Maurizio of Savoy. It was there that he met the madrigal composer Sigismondo d'India as well as the keyboard composer Girolamo Frescobaldi.
Rossi's two books of madrigals, which have only comparatively recently come to scholarly attention, were likely written during this period. Rossi's madrigal output from this period is remarkably chromatic, to a level matched only by the music of such experimental composers as Carlo Gesualdo.
