Knockout is a term used by Total Nonstop Action Wrestling (TNA) to refer to its female talent. The term is applied universally to wrestlers, backstage interviewers, and managers/valets. The term Knockouts is relatively new and was not used when Total Nonstop Action Wrestling debuted in 2002. The name originated from a DVD release in 2006 by the company, Knockouts: The Ladies of TNA Wrestling, Vol.1, which focused on its then-current female stars. The name "Knockouts" as a catchall name for the women stuck after that.
