Queen Seonui (Korean: 선의왕후; 14 December 1705 – 12 August 1730) of the Hamjong Eo clan, was the second wife of Yi Yun, King Gyeongjong, the 20th Joseon monarch.
They would eventually become the great-grandparents of Hong Hyeon-ju; the husband of Princess Sukseon, a daughter of King Jeongjo and Royal Noble Consort Su of the Bannam Park clan.
When her husband ascended to the throne and became the 20th Joseon monarch (temple name: Gyeongjong) in 1720, she automatically became queen consort.
The Noron faction and his step-mother, Queen Dowager Hyesun pressured him to appoint Prince Yeoning as his heir.
After her death, Jeoseung Hall was accommodated and converted into living quarters for Crown Prince Sado to which the name was changed to Chwiseondang (취선당), and was also a Soju room.
