Teresa Scanlan won a $50,000 scholarship and a yearlong run with the crown at the competition Saturday night at the Planet Hollywood casino and resort in Las Vegas.
She is the youngest Miss America since the pageant's first competition in 1921, which Margaret Gorman of the District of Columbia won at age 15.
Miss Arkansas Alyse Eady won $25,000 as first runner-up, while Miss Hawaii Jalee Fuselier won $20,000 for third place.
It was the pageant's 90th anniversary.
