O Ta-ryŏn

O Ta-ryŏn (856–944) was a Korean nobleman from Naju during the Later Three Kingdoms period. He was the father of Queen Janghwa and the father in-law of Wang Kŏn, the founder of the Goryeo dynasty, and the maternal grandfather of Hyejong of Goryeo, son of Queen Janghwa and Wang Kŏn. O Ta-ryŏn was an early supporter of Wang Kŏn, aiding him in the conquest of the Naju area.

O Ta-ryŏn was the son of O Pu-don. His family was thought to be wealthy maritime traders of non-aristocratic origins, similar to that of Wang Kŏn's ancestors. The character of pu in his father's name means wealth, symbolizing the wealth of Naju O clan. O Ta-ryŏn married the daughter of a local Silla sagan Yŏn Wi, who was presumably from a powerful local hojok family.
