Vira Bahu I (1196) was son of Nissanka Malla and king of the Kingdom of Polonnaruwa, in present day Sri Lanka. He came to the throne after his father's death, however only managed to reign for less than a day, being crowned at night and slain at dawn by the commander-in-chief of the army, Tavuru Senevirat on the grounds that he was a son not equal to his father.
