Queen Sado of the Park clan (; ? – February 614) was a Queen Consort of Silla as the spouse of king King Jinheung of Silla, and the mother of his successor, King Jinji of Silla. According to the disputed text Hwarang Segi, she was regent during the minority of her grandson King Jinpyeong but her regent is not mentioned in the historical texts Samguk sagi or Samguk yusa. She later became a Buddhist nun under the name Myobeop .
She was born to Park Yeong-sil and Princess Okjin of the Gyeongju Kim clan. She became the consort of the king early. The Hwarangsegi chronicle claimed that she married the king as early as the age of seven. During the last years of her husband's reign, he entered the temple of Yeongheungsa, and she followed him there.
In 576 her spouse died, and was succeeded by their son. According to Hwarang Segi: It is said that he was dethroned by his mother, Queen Sado, for refusing to marry her niece (in some accounts, sister) Mishil. He made a promise to marry her and make her his Queen once he became a king but had a change of heart as soon as he took over the throne. He lost interest on her after falling deeply in love with another woman. They spread a rumor that heavens has forsaken Silla for having an immoral king, thus resulted for them losing their lands against the Baekje. They asked him to abdicate in order to appease the heaven. He was then sent to confinement and died 3 months later. His nephew who was only 10 years old at that time, was then announced as a new king but since he was still too young to rule, Queen Sado acted as his regent for years.
Her grandson was a minor, and she became regent during his minority. Since King Jinpyeong was only 13 years old when he ascended the throne, Queen Dowager Sado, served as a regent until he reached the legal age in 584. However, Queen Sado still refused to give him full control of Silla even after he reached the legal age. She appointed Noribu, as the Sangdaedeung and Hujik as the head of the Military. Noribu died on December of 588, Sueulbu became the next Sangdaedeung after him. King Jinpyeong relied heavily on these two chief officials to solidify his kingdom in both internal affairs and international relations. He also gave the rank of Galmunwang to his brothers Baekban and Gukban, to solidify his power in the court.
