Dorotea Gonzaga (6 December 1449 – 20 April 1467) was an Italian noblewoman and Princess of Mantua. She was the daughter of Ludovico III Gonzaga, Marquess of Mantua and Barbara of Brandenburg.
In 1466, Dorotea was about to marry Galeazzo Maria Sforza, but the engagement was called off and she died in 1467. Her former fiancé married Bona of Savoy.
Galeazzo Maria Sforza (24 January 1444 – 26 December 1476) was the fifth Duke of Milan from 1466 until 1476. He was born to Francesco Sforza, a popular condottiero and ally of Cosimo de' Medici who would gain the Duchy of Milan in 1450, and Bianca Maria Visconti, Duchess of Milan on her own right. Sforza was betrothed into the Gonzaga family; after the engagement with Dorotea Gonzaga was called off, he married Bona of Savoy.
