Miss USA 2008 was the 57th Miss USA pageant, held in Las Vegas, Nevada on April 11, 2008. At the conclusion of the final night of competition, Crystle Stewart of Texas was crowned the winner by outgoing titleholder Rachel Smith of Tennessee. Crystle represented the United States at the Miss Universe 2008 pageant, which was held in Vietnam, where she placed in the Top 10. This was also the first time in the pageant's 56-year history that two consecutive women of African Americans have been crowned.
The pageant was held at the Theatre for the Performing Arts, a 7,000-seat theater located in the Planet Hollywood Resort and Casino. The theater was also the location of Miss Universe 1991 and 1996 pageants. This is the first time that the Miss USA pageant was held in Nevada.
For the first time, the competition was broadcast in High Definition.
Brother/sister duo Donny and Marie Osmond hosted the live telecast for the first time, and Finger Eleven performed their single "Paralyzer". Rihanna's song Umbrella was used during the evening gown competition.
During the final show on April 11, the fifteen delegates with the highest average scores from the preliminary competition were announced. The top fifteen competed in the swimsuit competition. The top ten delegates from swimsuit competed in evening gown. The top five delegates from the evening gown competition (not averaged composite scores from both competitions) competed in the final question round to determine the winner. The judges' composite score was shown after each round of competition for only the second time since 2002.
One delegate from each state and the District of Columbia were chosen in state pageants held from June 2007 to January 2008.
