Maria Palaiologina

Maria Palaiologina (died 1355) was queen consort of Serbia as the second wife of King Stefan Uroš III Dečanski, whom she married in 1324. The daughter of John Palaiologos, Byzantine governor of Thessaloniki, and a great-niece of Emperor Andronikos II, she bore Dečanski a son, Simeon Uroš, and daughters Jelena and Teodora.

After Stefan Dušan deposed Dečanski, who was killed at Zvečan in 1331–1332, Maria sought Byzantine backing to place Simeon on the throne, in vain. She took the veil as Marta and died in 1355.
