George V the Brilliant (Georgian: გიორგი V ბრწყინვალე, romanized: giorgi V brts'q'invale; also translated as the Illustrious, or Magnificent; 1286–1346) of the Bagrationi dynasty, was the king (mepe) of the Kingdom of Georgia from 1299 to 1302 and again from 1314 until his death in 1346.
He was raised in Samtskhe, at the court of his maternal grandfather, Beka I Jaqeli, who held the position of Mandaturtukhutsesi. In 1299, Ghazan appointed the young George to rule in opposition to his brother, King David VIII. Although proclaimed king, his authority extended only over Tbilisi, which earned him the title “King of Tbilisi.” In a similar manner, Ghazan later used another brother of David VIII, Vakhtang III, who reigned from 1302 to 1308.
