Dorothy Garai (Serbo-Croatian: Doroteja Gorjanska/Доротеја Горјанска, Hungarian: Garai Dorottya; died between 19 and 24 September 1438) was a Hungarian noblewoman who became Queen of Bosnia upon her marriage to King Tvrtko II in 1428. She functioned as art patron and exerted significant influence over her husband, especially over his relations with church officials, which earned her considerable notoriety in monastic circles. The marriage was harmonious, but childless and cut short by her death in her twenties.
