Giorgio Sisgoreo, also known as Juraj Šižgorić ( or Sisgoritus, ; ca. 1445–1509) was a Latinist poet from Venetian Dalmatia. He was the first humanist from Šibenik and the central personality of Šibenik's humanist circle and also one of the most important figures in 15th-century cultural life of the Croatian people. His Elegiarum et carminum libri tres ("Book of elegies and poems", Venice, 1477) is considered the first published book by a Croatian poet. American historian J. V. A. Fine emphasizes that Šižgorić and Vinko Pribojević did not consider themselves to be Croats, but rather Slavic-speaking Venetians.
