Giacomo Pacchiarotti (; 1474 – 1539 or 1540), or Jacopo Pacchiarotto (), was an Italian painter.
Life and works
He was born in Siena, and worked there. Bernardino Fungai may have been his teacher; Pacchiarotti's style is influenced by Fungai, as well as Matteo di Giovanni, Perugino, and Signorelli. He fled to France where he joined Rosso Fiorentino in the work at Fontainebleau. He may be the Girolamo di Pacchia mentioned by Vasari in his chapter on il Sodoma.
