Bagrat IV (1018 – 24 November 1072), of the Bagrationi dynasty, is the King of Georgia from 1027 to 1072.

During his long and eventful reign, Bagrat seeks to repress the great nobility and to secure Georgia's sovereignty from the Byzantine and Seljuqid empires.

In a series of intermingled conflicts, Bagrat succeeds in defeating his most powerful vassals and rivals of the Liparitid family, bringing several feudal enclaves under his control, and reducing to vassalage the kings of Lorri and Kakheti, as well as the emir of Tbilisi.

Like many medieval Caucasian rulers, he bears several Byzantine titles, particularly those of nobelissimos, curopalates, and sebastos.
