She married Matthew Gilmour Saturday afternoon.
"People" magazine reports the newlyweds, who met while doing Mormon missionary work in Paris, will honeymoon at an undisclosed location then will return to Salt Lake City to live.
Smart became a household name after she was kidnapped from her Salt Lake City home in 2002.
She was 14 years old at the time.
She was held by Brian David Mitchell and his wife for nine months before being rescued.
At Mitchell's trial, Smart testified that she was taken to California during her captivity then was returned to Utah.
Mitchell and his wife, Wanda Eileen Barzee, have since been convicted for the crime.
Smart has become an advocate for crime victims.
