Vratko Nemanjić

Vratko Nemanjić (fl. 1325–1355) was a Serbian nobleman of the Nemanjić dynasty's Vukan branch, the son of grand župan Vratislav and great-grandson of Vukan Nemanjić. A companion of Stefan Dušan, in 1342 he and vojvoda Oliver led a Serbian army against Serres in support of John VI Kantakouzenos, but the siege collapsed when dysentery killed some 1500 of their men.

His daughter Milica married Prince Lazar around 1353. Serbian epic poetry remembers him as Jug Bogdan, the aged hero of the Kosovo cycle.
