Total Nonstop Action Wrestling Grand Slam

=== Impact Wrestling (2009) ===
A.J. Styles – the first Impact Wrestling Grand Slam winner and the only man to be a Grand Slam Champion in both Impact Wrestling and WWE
The first Impact Wrestling Grand Slam winner, then known as the Total Nonstop Action Wrestling (TNA) Grand Slam, was crowned on March 15, 2009, at TNA's Destination X pay-per-view event. At said event, then three-time TNA Triple Crown champion A.J. Stylesdefeated Booker T for the TNA Legends Championship. On the March 19 episode of TNA's primary television program, TNA Impact!, announcer Mike Tenay stated that Styles had become the first TNA Grand Slam winner by capturing the World Heavyweight (NWA or TNA), World Tag Team (NWA or TNA), X Division, and Legends Championships (The Legends Championship was subsequently renamed the Global, Television, and King of the Mountain Championship, before being fully retired).
Under TNA's definition of the Grand Slam, wrestlers are eligible to be a multiple Grand Slam winner each time they complete a new circuit. Thus far, only A.J. Styles has won the Grand Slam on more than one occasion.
On August 15, 2016, the TNA King of the Mountain Championship was once again retired when Lashley unified the title into his TNA World Heavyweight Championship. In a March 26, 2018, article on the Impact Wrestling website, the eligibility of the Impact Grand Championship, which replaced the King of the Mountain Championship, as a Grand Slam title was confirmed. However, on June 4, 2018 during a press conference Austin Aries unified the Grand Championship with the World Championship. Thus any future Grand Slam winners will be limited to those who had already held either the Legends/Global/TV/King of the Mountain title or Grand Championship.
