Jung Ryeo-won (Korean: 정려원; born January 21, 1981) is an Australian actress and former singer based in South Korea.

Jung's morale was at a low in 2002, saying she sometimes felt alienated from her fellow Koreans, and was uncomfortable with the sexy clothes she was made to wear as a singer.

[7][8] Jung was praised for her portrayal of a fragile but good-natured character who fights for the hero's love,[3] and eventually became one of the few successful singer-turned-actresses in the country.

[9] Her follow-up series Autumn Shower received low ratings,[10] but she rebounded with Which Star Are You From?, in which she played a country bumpkin living in the mountains of Gangwon Province.

[11][12] She was cast in her first movie leading role as a girl with multiple personality disorder in 2007's Two Faces of My Girlfriend,[13][14] and though it was not a box office hit, she won Best New Actress at the Blue Dragon Film Awards.

[27][28][29] She then starred in Never Ending Story, a romantic comedy about two people diagnosed with terminal illness who decide to spend their remaining time together preparing for death.

[37] Jung next played an impatient and careless radio producer in the cable series Bubble Gum in 2015; she and co-star Lee Dong-wook previously appeared together in the 2003 sitcom Do the Right Thing.

[38] In 2017, she starred in the legal procedural drama, Witch at Court, playing a highly ambitious prosecutor who speaks her mind and is known for her aggressive investigation tactics.

[46] In March 2014, Jung began hosting Art Star Korea on cable channel StoryOn, an audition program/reality show featuring contemporary artists.
