|Miss USA 2003|
|Date||March 24, 2003|
|Venue||San Antonio Municipal Auditorium, San Antonio, Texas|
Miss USA 2003 was the 52nd Miss USA pageant, held at the San Antonio Municipal Auditorium in San Antonio, Texas on March 24, 2003. It was the first time it had been held in this state since 1996 when the pageant was held in South Padre Island. It was the latest it had been held since 1986, as previous pageants had been held in February or early March and this was the first Miss USA to be broadcast on NBC, replacing CBS, which had broadcast the pageant since 1963.
The pageant was won by Susie Castillo of Massachusetts, who was crowned by outgoing queen Shauntay Hinton of the District of Columbia. The format reverted to a Top Ten who competed in swimsuit and evening gown, although, as with 2002, there was no interview competition for the semi-finalists. This would be the last year where a top ten was called until 2017. The following Miss Universe Organization pageant, Miss Universe 2003 and onward, fifteen semi-finalists have been called each year.
Daisy Fuentes co-hosted the event for the first time (although she had been a color commentator in 1995), joined by Billy Bush who would also host the 2004 and 2005 events, as well as the Miss Universe pageants all three years. Color commentary was added by reigning Miss USA Shauntay Hinton. Entertainment was provided by Burn The Floor.
