Luciano Laurana (Lutiano Dellaurana, Croatian: Lucijan Vranjanin) (c. 1420 – 1479) is an architect and engineer from the historic Vrana settlement near the town of Zadar in Dalmatia, (today in Croatia, then part of the Republic of Venice).

After education by his father Martin in Vrana settlement, he works mostly in Italy during the late fifteenth century.

He is the principal designer of the Palazzo Ducale of Urbino and one of the main figures in fifteenth-century Italian architecture.

He considerably influences the development of Renaissance architecture.

His projects are accompanied with notes in the Croatian glagolitic script, as witnessed by the famous Bernardo Baldi.

He is a relative of the sculptor Francesco Laurana.
