William James Hung Hing Cheong (Traditional Chinese: 孔慶翔, Simplified Chinese: 孔庆翔, Cantonese Yale: Hung2 Hing3 Cheung4, Pinyin: Kǒng Qìngxiáng; born January 13, 1983), commonly known as William Hung, is an American singer who gained fame in early 2004 as a result of his off-key audition performance of Ricky Martin's hit song "She Bangs" on the third season of the television series American Idol.

Hung's spirited audition to be the next American Idol inadvertently won the support of many fans. Hung became popular enough to perform on many popular shows, and even secured a record contract with Koch Entertainment in 2004. His fame became the subject of much controversy as both he and his fans were accused of promoting and endorsing racial stereotypes against Asians, although he did not seem to notice or even care about the possible implications of his popularity, believing he was living his dream.

He brought his own career as a musician to an end when in 2011 he accepted a job opportunity as a technical crime analyst, and decided to pursue it instead of music. Since then, Hung has reflected positively on his pop music career, and has moved on.
