Eudokia Palaiologina Tzamplakonissa

Eudokia Palaiologina Tzamplakonissa was a fourteenth-century Byzantine noblewoman, the daughter of Constantine Palaiologos. She married Demetrios Tzamplakon, megas stratopedarches; the Tzamplakons were landowners around Serres, where Eudokia probably first lived.

In 1345 she was with her husband at Serres, and after the city fell to the Serbs she followed him to Chrysoupolis, where Demetrios remained until 1360. In 1362 the couple donated part of an estate near the Gallikos river to Vatopedi monastery; the surviving charter carries her signature.
