The 2013 CrossFit Games, the seventh CrossFit Games, were held on July 24–28, 2013, at the StubHub Center in Carson, California. The men's competition was won by Rich Froning Jr., the women's by Samantha Briggs, and the Affiliate Cup by Hacks Pack UTE.

The CrossFit Games is an annual athletic competition owned and operated by CrossFit, LLC. Athletes compete in a series of events at the Games, which may be various standard CrossFit workouts consisting of metabolic conditioning exercises, weightlifting, and gymnastics movements, as well as a range of activities from other sports such as swimming, road cycling and strongman. The events generally are not revealed before the Games, can include unexpected elements to challenge the athletes' readiness to compete, and they are designed to test the athletes' fitness using CrossFit's own criteria. Winners of the CrossFit Games earn cash prizes and the title of "Fittest on Earth."
