Carlo Borzio (* at Lodi, near Milan; 1656-1695) was an Italian composer. As a member of the clergy he was the head of the cathedral of Lodi and later its congregation. His works include operas and oratorios many of them texts by his friend Francesco de Lemene who also came from Lodi.
Around 1656 Borzio appeared in improvised comedies at the poet's house. His most important work is ''Il Narciso'' which was revived.
