Ruđina Balšić (Serbian Cyrillic: Руђина Балшић, Albanian: Rugjina Balsha; fl.

1396–1420) was a Zetan noblewoman and ruled upon today Montenegro and Albanian territory from the Balšić family.

In 1420, during the Second Scutari War, she surrendered Budva to the Venetians without any resistance and moved to Dubrovnik with the town's treasury.

While the Venetians prolonged negotiations with Ruđina hoping to get a better price, the Ottomans captured Vlorë in June 1417.

[11] After the Ottoman conquest of Vlorë, Ruđina had to flee, first to Corfu[11] and then to Zeta, which was ruled by her nephew, Balša III, who entrusted her with the governorship of the coastal town of Budva in 1418.
