Bagrat I (Georgian: ბაგრატ I) (died 876), of the Bagratid dynasty, was a presiding prince of Iberia (modern Georgia) from 830 until his death.

Bagrat inherited from his father Ashot I the office of presiding prince of Iberia and the Byzantine title of curopalates.

The 10th-century Georgian writer Giorgi Merchule maintains that Bagrat was confirmed as curopalates, following his father, with the agreement of his brothers — Adarnase, and Guaram.

[2] Bagrat I found himself in a constant struggle with the Arabs, the Abasgians and the Kakhetians over the possession of central Iberia (Shida Kartli) and especially the Emirate of Tbilisi.

In August 853, Bagrat joined the Caliph's second expedition against Sahak, this time led by Bugha the Turk who took Tbilisi and had the emir executed.
