Giorgi II Dadiani (Georgian: გიორგი II დადიანი; died 1384) was a member of the House of Dadiani and eristavi ("duke") of Odishi in western Georgia from 1345 until his death.
Giorgi II succeeded on the death of his father, Mamia I Dadiani, in 1384, as duke of Odishi, latter-day Mingrelia.
[1] Beyond Odishi proper, Giorgi held sway over Guria and Svanetia.
Giorgi and his wife, Marikhi, are depicted in a fresco in the northern wall of the Bedia Cathedral, in his possessions in Abkhazia, which he had renovated.
[2] Giorgi had a wife, Rusudan, and two sons, of whom Vameq I succeeded him in Odishi; the other, Kakhaber, was appanaged with Guria with the title of Gurieli.
