She attended Maʻemaʻe Elementary School and Kamehameha Schools in Honolulu, Hawaii. Hu has held a lifelong interest in singing and dancing and has also been interested in martial arts since her early childhood. Hu's cousin was a successful model in Japan, and Hu decided to follow her example. Kelly Hu won the title of Miss Hawaii Teen USA and competed in the Miss Teen USA 1985 pageant, becoming the Miss Teen USA pageant's third titleholder in history and its first Asian American winner. Hu has mentioned in interviews that her mother had told her America was not ready for an Asian as such a prominent role model. She discovered after winning that she was prohibited from appearing in non-contest related activities for the year of her reign, though this rule was changed in later years. Hu modeled in Japan and Italy, and became well known in the latter as the star of a series of television advertisements for Philadelphia brand cream cheese, playing a young Japanese college student named Kaori. Hu won the title of Miss Hawaii USA in 1993, becoming the first former Miss Teen USA to win a Miss USA state title. In the 1993 Miss USA pageant, held in Wichita, Kansas, Hu entered the top 10 in second place, after winning the preliminary interview competition and placing second and third, respectively, in swimsuit and evening gown. She then made the top 6 ranked second, winning the top 10 evening gown competition and placing second in swimsuit.
