(d. 1665), archbishop of the Italian diocese of Fermo. He was sent to Ireland as papal nuncio in 1645, during the Confederate War, charged with the impossible task of achieving the public restoration of Catholicism by agreement with Charles I. When his agreement with the king's agent, the earl of Glamorgan, collapsed, the confederate supreme council proceeded with the Ormond peace (1646). Rinuccini had the Ormondists imprisoned, assumed interim headship of the confederate administration, and launched an offensive against Dublin. However, the campaign was crippled by conflict between Preston and Owen Roe O'Neill, whom the nuncio had at one point physically to prevent from coming to blows.
