Vojihna Nemanjić of Drama or simply Vojin of Drama (Serbian Cyrillic: Војихна[A] ; ca 1298–1360), was a Serbian feudal nobleman, member of the collateral branch of Nemanjić dynasty, ruling family of the medieval Serbia, that rose through the ranks and became one of the most acclaimed military commanders (voivode[2]) and princes of Stephen Uroš IV Dušan of Serbia.

[3][4] During this period, he was ruling the entire region of Drama (today in Northwestern Greece) as its Lord.

In 1344, Dušan sent a small army led by Voivode Preljub to intercept the Aydin Turks.

In this southeasternmost part of his Empire, Dušan appointed Voihna as governor of Drama, not far from Serres, before November 1345.

[5] Immediately after Dušan's death (20 December 1355), his wife Empress Helena was found in Serres.

[3] How the Empress ended up in Serres and started to rule it is unknown, it exists sources saying she was in the region staying away from the harsh winter in the north, just when her husband died.

[11] Vojihna planned to release Matthew for a ransom, but soon realized that Emperor John V Palaiologos was willing to offer a far greater sum.

[1] Matthew renounced his territory and imperial title in December 1357 and John V continued to rule as sole Emperor.
