Baron István Dobó de Ruszka (c. 1502 - Szerednye (today, Середнє (Szerednye / Serednie, Ukraine), mid-June 1572) was a Hungarian soldier, best known as the successful defender of Eger against the Ottomans in 1552. Dobó was a member of the Hungarian land-owning nobility, with holdings in northern Hungary. In the dynastic succession struggles after the Battle of Mohács in 1526, Dobó was consistently on the side of the Habsburg KingFerdinand I rather than that of John Zápolya.
