Lovro Marinov Dobričević or Lorenzo Bon, Lorenzo di Marino da Cattaro (c. 1420 – 1478) was a painter from Venetian Dalmatia. Born in Kotor, Republic of Venice (now Montenegro), he studied art in Venice before returning to Ragusa (modern-day Dubrovnik) to work. He first started to paint in the Serbian Orthodox Savina Monastery in Zeta and Serbian Despotate (now Montenegro) in the mid-15th century. Also, his paintings may still be seen in both the Dominican and Franciscan monasteries in the city of Dubrovnik; one of his altarpieces may still be seen in a church in Slano. He was part of a group called the Ragusan School of Painting which included Blaž Jurjev Trogiranin, Jovan Ugrinović, Mihajlo Hamzić (Michael Joannis Theutonici) and Nikola Božidarević (Nicolò Raguseo). They specialized in painting icons and iconostasis for both churches and monasteries of the Serbian Orthodox Church in Montenegro and Bosnia-Herzegovina, and Polyptych of the Roman Church tradition in Dubrovnik. He died in Dubrovnik.
