Queen Sinjeong (Korean: 신정왕후; Hanja: 神貞王后; 9 January 1809 – 23 May 1890), of the Pungyang Jo clan, was the only wife of Crown Prince Hyomyeong and mother of Heonjong of Joseon. She was never formally a Queen but was known as Queen Dowager Jo (조대비) during the reign of her son before Cheoljong of Joseon granted her a proper title, Queen Dowager Hyoyu (효유왕대비).
After the previous king died, she was known as Grand Queen Dowager Hyoyu (효유대왕대비), and served as nominal regent during Gojong's minority, between 1864 and 1873. Although she left all de facto power to the King's father, Grand Internal Prince Heungseon, and only kept the formal title.
