Rostom (Georgian: როსტომი) (1571–1605), of the Bagrationi dynasty, was a king (mepe) of Imereti in the periods of 1588–1589 and 1590–1605.

Rostom's authority was defied, however, by his ostensible vassal Giorgi II Gurieli, prince of Guria, who employed an Ottoman force to dethrone the king in favor of Rostom's relative Bagrat IV.

The eastern Georgian king Simon I of Kartli exploited the situation and brought most of Imereti under his control.

Rostom fled to Mingrelia, with Manuchar I Dadiani, who rejected Simon's ultimatum and moved into Imereti.

His authority was largely nominal though, and the power was effectively held by an aristocratic élite, notably by the prince of Mingrelia.
