Lovro Marinov Dobričević or Lorenzo Bon, Lorenzo di Marino da Cattaro[1] (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.

[2] 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).
