Giovanni Andrea Bussi (1417–1475), also Giovan de' Bussi or Joannes Andreae, was an Italian Renaissance humanist and the Bishop of Aleria. He was a major editor of classical texts and produced many incunabular editiones principes. In his hands the preface was expanded from its former role as a private letter to a patron, to become a public lecture, and at times a bully pulpit.
