Hough was born in Orem, Utah, the youngest of five children in a Latter-day Saints (Mormon) family. Her parents are Marianne and Bruce Hough; her father was twice chairman of the Utah Republican Party. Her brother, Derek Hough, is also a professional dancer. She also has three older sisters: Sharee, Marabeth and Katherine.

Hough was one of the Million Dollar Dancers in the 2006 ABC game show called Show Me the Money. She won season four of the U.S. edition of Dancing with the Stars with her partner Olympic gold medal-winning speed skater Apolo Ohno, making Hough the youngest professional dancer to win on the program. On November 27, 2007, Hough and her partner, three-time Indianapolis 500 champion Helio Castroneves, became the winners of season five. Hough returned for season six with radio host/comedian Adam Carolla, but they were eliminated in week four. In July 2008, Hough was nominated at the 60th Primetime Emmy Awards in the category of "Outstanding Choreography" for her Mambo "Para Los Rumberos" (performed with partner Helio Castroneves) on Dancing with the Stars.  On August 25, 2008, the cast of season seven was announced, and Hough was partnered with Hannah Montana actor Cody Linley. She felt abdominal pains during their jitterbug performance on October 27, 2008 and was immediately rushed to a hospital following the encore performance. She subsequently had surgery to have her appendix removed, causing her to miss several performances; Edyta Sliwinska stood in for her. Hough returned to the show, although the pair was ultimately eliminated in the Semifinals Competition. She appeared on the November 12 results show dancing the jive to "Great Balls of Fire" with her brother for the "Design-A-Dance" contest.  On November 20, 2008, Hough told Ryan Seacrest on his radio show she would not be returning to Dancing with the Stars, for the foreseeable future, in order to further her music career. However, she did return for season eight, partnering with boyfriend at the time, country singer Chuck Wicks. They were voted off in week eight of the competition and came in sixth place. On October 11, 2011, Hough returned to Dancing with the Stars and danced with her Footloose co-star Kenny Wormald twice, as well as her brother. She returned again on May 15, 2012 in a dance performance to promote her film Rock of Ages. On October 7, 2013, she was guest judge in place of Len Goodman, which was the first time a former pro dancer came back to judge. In September 2014, she returned as the show's permanent fourth judge.
