Giulio Cesare Rubino (fl. 17th and 18th centuries) was an Italian composer of whom little biographical information is known. His surviving compositions include a psalm Confitebor[1] and some secular cantatas. One cantata Oh cielo, oh ammore was composed for lady Clelia Caracciolo, marchioness of Arena.[2][3] The cantata Lena was recorded by Marco Beasley.
