Mithridates I (Mihrdat I) (Georgian: მითრიდატე I) was the 1st-century king (mepe) of Iberia (Kartli, Georgia) whose reign is evidenced by epigraphic material.

Mithridates I is ignored by the medieval Georgian chronicles which instead, report a joint rule of Kartam (Kardzam) and Bartom (Bratman), in the time when Vespasian's destruction of Jerusalem in 70 spurred a wave of the refugee Jews to Iberia; Kartam and Bartom were supposedly succeeded by their sons, Parsman and Kaos, and grandsons, Azork and Armazel.

[2] Several modern scholars, such as Cyril Toumanoff, consider the Iberian diarchy a pure legend and a "deformed memory of the historical reign of Mithridates I".

[3] Of these royal pairs, Professor Giorgi Melikishvili identifies "Azork" as Mithridates I's possible local name and "Armazel" as a territorial epithet, meaning in Georgian "of Armazi".

[5] Some modern scholars identify Mithridates I with the King Flavius Dades, known from a single Greek inscription around the edge of the base of a large silver dish found at Armazi.
