Yoo Ha-na (born March 22, 1986 in Seoul, South Korea) is a South Korean actress. She has starred alongside Jimmy Lin in the Taiwanese TV drama series My Lucky Star, and has also appeared in the music video for "White Windmill" by Taiwanese singer Jay Chou.
Yoo Ha-na originally got her start in the entertainment business by posing for pictures in various magazines in South Korea. One of Yoo's photos caught the eye of Chen Yu-shan (producer for the Taiwanese drama My Lucky Star) from a magazine she picked up while at a beauty salon. Chen made arrangements afterwards with Yoo's agent to fly Yoo from South Korea to Taiwan to audition for My Lucky Star, which landed Yoo the lead female role in that drama. At the time, Yoo had already appeared in the music video "White Windmill" for Taiwanese singer Jay Chou.
Yoo went on to appear in a few Taiwanese films such as Exit No. 6 before returning to South Korea, where she starred in TV dramas such as My Too Perfect Sons, First Wives' Club, and Paradise Ranch.
