Giacomo Rocca (or Rocchetti) was an Italian painter of the late-Renaissance or Mannerist period. He was a pupil of Daniele da Volterra, and aided him in completion of frescoes for the first chapel on the right of Santa Maria degli Angeli in Rome. Rocca's biography is sketched in Giovanni Baglione's Le vite de' pittori, scultori et architetti dal pontificato di Gregorio XIII del 1572 in fino a tempi di Papa Urbano VIII nel 1642. //
