Giovanni Dalmata (Croatian: Ivan Duknović; c. 1440 – c. 1514), born Ioannes Stephani Duknovich de Tragurio, also known as Giovanni Duknovich di Traù in Italy and Ivan Stjepanov Duknović in Croatia, was a sculptor from Trogir, Dalmatia, who was mainly active in Rome, Hungary and his native country during the European Renaissance.
Dalmata was, with Mino da Fiesole and Andrea Bregno, one of the leading sculptors in Rome in the second half of the 15th century.
Around 1488–1490, Giovanni went to the Court of King Matthias Corvinus in Buda, where he stayed for a few years, mastering a number of works which were unfortunately all either destroyed or badly damaged (e.g. the Fountain of Hercules in Visegrád).
He is also the creator of the sculpture of St. Magdalene in the Franciscan monastery of St. Anthony on the nearby Čiovo island and worked with Nicolò Fiorentino and Andrea Alessi on the Renaissance Cippico Palace in Trogir.
A newly discovered work (The Virgin and Child, a marble relief) was offered on auction in London's Katz gallery Archived 2005-05-18 at the Wayback Machine and bought for £250,000 by Trogir City Museum.
