Nikola Božidarević (pronounced [bɔʒi-ˈdə:rɔvitɕˈ]; more commonly Nicholas of Ragusa (Italian: Nicolò Raguseo, Latin: Nicolaus Rhagusinus, Serbo-Croatian: Nikola Dubrovčanin c. 1460 – 26 November 1517/18), was a painter from Venetian Dalmatia at the turn of the Gothic in the Renaissance.

The son of the painter Božidar Vlatković of Slano, he was probably born in Kotor (today Montenegro) around 1460.

He was a hard-working and greatly sought-after man, as can be seen from numerous documents and contracts kept in the Dubrovnik archives.

Monasteries like the Franciscans in Cavtat and the Dubrovnik Dominicans commissioned works from him, as did noble families and individuals and some churches.

Of seventeen works by Nikola Božidarević recorded in the Dubrovnik Archives, only four paintings remain:[2] a triptych on a side altar in the Bundić Chapel of the Dominican monastery in Dubrovnik, The Annunciation in the art gallery of the Dominican church, the Đorđić family's altarpiece in the capitulary hall of the Dominican monastery, and another triptych in the Franciscan church on Lopud has also been ascribed to him.
