Francesco Cattani da Diacceto (16 November 1466 – 10 April 1522) was a Florentine Neoplatonist philosopher of the Italian Renaissance.

When he returned to Florence he became a disciple of Marsilio Ficino and a member of the intellectual group known as the Platonic Academy.

[3] Unlike Ficino, Diacceto tried to reconcile the philosophies of Aristotle and Plato.

[4] Also, he was not concerned with trying to Christianise Plato or Plotinus, so he provides a much clearer account of Neoplatonic magic and astrology; however, he appears to have been less interested in the subject than Ficino.

His grandson Francesco Cattani da Diacceto, bishop of Fiesole, attempted to collect and publish his works in both Latin and Italian, and commissioned Benedetto Varchi to write his biography.
