Queen Sunwon (순원왕후 김씨, 8 June 1789 – 21 September 1857) also known as Queen Dowager Myeonggyeong (명경왕대비) was a Queen consort of Korea as the spouse of Sunjo of Joseon. She served as regent of Korea from 1834–1841 and from 1849–1852.

She was a daughter of Kim Jo-sun (김조순, 1765–1832) of the Andong Kim clan. Her mother was a lady from the Sim clan (심씨).

In 1802, she married King Sunjo of Joseon as his first and only queen consort. Her husband died in 1834, and she became regent for her eight-year-old grandson, King Heonjong.

Queen Sunwon died at Changdeok Palace on 21 September 1857.
