Janet Nguyễn (born 1976) is the county supervisor from the first district in Orange County, California. She won her seat following an unprecedented special election where two Vietnamese-American candidates received half of the votes cast in a field of 10, separated from each other by only 7 votes. She was sworn in on March 27, 2007, after a lengthy court battle. She is the youngest person to be elected to the board of supervisors, the first woman to be elected from that district, and the first Vietnamese-American county supervisor in the United States. Prior to her election to the board of supervisors, she served as a city council member for Garden Grove.
Nguyen was born in Saigon, Vietnam. Her family joined millions of others in becoming boat people when she was five, coming to California in 1981. They first lived in San Bernardino, but settled in Garden Grove in 1990. She attended the University of California, Irvine, at first to become an obstetrician, but later majored in political science after she was inspired by then-supervisor Bill Steiner. She is married to Tom Bonikowski.
