Chloe Dao (Lao: ໂຄລອີ ດາວ; born July 1971) is a Vietnamese-American fashion designer and television personality who lives and works in Houston, Texas, United States. She won the second season of an American reality television series Project Runway with a thirteen-piece collection of women's evening wear.

Chloe Dao was born in Pakse, Laos, the sixth daughter to her ethnically Vietnamese (Kinh) parents. (Two younger sisters were born after her.) She, her parents, and her seven sisters escaped the Viet Cong in 1976, settled for a refugee camp in Thailand, and moved to Houston, Texas, in 1979. To support the family, Dao's mother had three jobs with limited understanding of the English language at the time, and Dao's father worked full-time.

Dao's parents desired her to become a doctor or lawyer. Instead, Chloe gained interest in fashion designing after she watched a CNN program Style with Elsa Klensch at age ten. She attended a school in the Aldine Independent School District. As a teenager, she modified vintage clothes from second-hand shops, and her first original work was her own prom dress. Then Dao attended the University of Houston as a business marketing major for three semesters and then Houston Community College under its fashion design program for one semester. She earned from the Fashion Institute of Technology a degree in pattern making and then worked for couture designers Madame Rossule and Melinda Eng amid her eight-year stay in New York City.

A 34-year-old entrepreneur and women's wear designer at the time, Dao entered the second season of Project Runway. She also was one of sixteen contestants and the only Texan of that season. Throughout Project Runway before the finale, she had won two challenges. In the final pre-Fashion Week challenge in the eleventh episode, Dao's "dove-gray" dress intended for supermodel Iman was criticized as "safe" and lost to Daniel Vosovic—whose dress was also what judge Nina Garcia deemed "safe" and "boring"—making him a finalist. Dao was one of two contenders for elimination, but then she secured her spot as one of top three.

For the Fashion Week, Dao's collection included several dresses with "puffed sleeves", "silhouettes with open backs", and brown pants "with a lace bodice and puffed-laceover [sic]". The collection also contained thirteen pieces total, including "minidresses and short skirts" in "chocolate brown, pearl blue and sea green" colors. Dao chose Diana Eng, one of eliminated contestants of the season, as her assistant to finish the thirteenth outfit assigned to complete the collection.

Dao won the season against the first runner-up Daniel Vosovic and the second runner-up Santino Rice. For that, she further earned $100,000 to start her clothing line, a $24,000 silver Saturn Sky roadster—coupé sports car—that she received in July 2006, an Elle magazine coverage, and a mentorship with Banana Republic. To use the mentorship, she contacted the Banana Republic's design team via phone.

When the second season originally aired, Dao's win surprised "many viewers", said Jay Bobbin of Zap2It. Karla Peterson of The San Diego Union-Tribune named Dao potentially "the most down-to-earth reality show contestant ever" by the end of January 2006. Timothy Gunatilaka of Entertainment Weekly found her not deserving to win as second runner-up Santino Rice, whose finale collection Gunatilaka admired the most out of three. Gunatilaka further found Dao "too safe" throughout the season and her collection "sleek and sexy" but "also safe" and reminiscent of Banana Republic. He further wrote about her win that "corporate-speak beat out true creativity."

Tenley Woodman of Boston Herald named her "the most boring contestant" and found her collection "less than exciting" when she won. Nevertheless, Woodman noted "her business sense and aptitude for understanding women's desires in clothing" as judges' reasons to crown her over two other finalists, despite being their "safe and productive choice", contrary to the previous season's "outrageous winner" Jay McCarroll.
