Total Nonstop Action Wrestling (TNA) is an American professional wrestling promotion founded by Jeff Jarrett and his father Jerry Jarrett in the month of May 2002. The recent majority share owner is Panda Energy International. The company, that trades as TNA Entertainment, LLC, operates out of Nashville, Tennessee, with an office in Orlando, Florida.

TNA showcases Lucha Libre style Cruiserweight action under the X Division, while also concentrating on the heavyweight division, featuring heavyweights such as Samoa Joe, Booker T, Scott Steiner and Kurt Angle, primarily under a sports entertainment style. Recently, several shoot-style matches have been featured in TNA.

TNA was a member of the National Wrestling Alliance, with the company known as NWA Total Nonstop Action. TNA was granted exclusive rights to both the NWA World Heavyweight Championship and the NWA World Tag Team Championship. TNA withdrew from the NWA in 2004, but was permitted to continue to use the championships until the NWA abrogated the agreement in May 2007.

TNA is the first American promotion to use a hexagonal wrestling ring exclusively as opposed to the more conventional four-sided ring. The organization also employed the unconventional rule that a championship can change hands as the result of a disqualification or count out. This rule has since been slowly phased out. For shows taking place in the TNA Impact! Zone, two separate entrance ramps are used for heels and faces.

TNA began airing TNA Impact that started on June 4, 2004 on Fox Sports Net and it soon replaced the weekly pay-per-views as their primary broadcast while the monthly events became the main source of revenue. The contract was not renewed one year later with the show getting consistent low ratings.
