Seonjeong

Queen Seonjeong of the Chungju Yu clan (; 980–?) was a Goryeo royal family member as the paternal granddaughter of Prince Sumyeong and maternal granddaughter of King Gwangjong who became a queen consort through her marriage with her maternal first cousin or paternal second cousin, King Mokjong as his first and primary wife. From this marriage, Queen Seonjeong became the sixth reigned Goryeo queen who followed her maternal clan after Queen Mundeok, her mother.

Biography After her biological father's death, her mother remarried again with Seongjong of Goryeo who is believed to have raised her since she was young and treated her not so different like his own daughters, which made some believed that the future Queen was King Seongjong's real daughter.

Although her age was unknown at this time, and seeing that she married Wang Song (grandson of King Gwangjong and Queen Daemok), they must have been at the similar age or slightly older. They were believed to grow up together almost like a sibling, also Mokjong was said that he liked to follow her as she had taken care of him since childhood.

In 997, King Seongjong died and was succeeded by her husband. She then followed her grandmother, Queen Sinmyeong's clan. Her mother-in-law, Queen Heonae overtook the new King's throne and became a regent since he was not interested in politics.
