Rebecca Marie Bross (born July 11, 1993) is an American former artistic gymnast and six-time World Championship medalist.

At the 2006 U.S. Nationals, Bross placed fourth all-around, which also qualified her to the Junior Pan American Championships team.

She competed with WOGA teammate Nastia Liukin at the Pacific Rim Championships, where she won gold medals in the all-around and on beam, bars and floor.

On July 25, 2009, at the Covergirl Classic in Des Moines, Iowa, Bross competed on the uneven bars, scoring a 13.150 (.050 better than her teammate Ivana Hong), but she was unable to compete on floor, beam or vault because of an ankle injury suffered during practice a few days earlier.

In August 2009, Bross finished third all-around behind Bridget Sloan (first) and Ivana Hong (second) at the U.S. National Championships.

The following October, at the World Championships in London, England, Bross qualified in first place into the all-around final.

Needing only a 12.925 to clinch the gold, she fell on her final tumbling pass on floor and just missed that score (the judges awarded her a 12.875).

In event finals, Bross clinched the bronze on the uneven bars and tied with China's Deng Linlin for the silver on the balance beam behind Romania's Porgras.

Sports commentators speculated that Bross's defeat at the trials would likely be a career-ending one because of her previous injuries and age.
