Grand Slam Champion

A Grand Slam Champion in professional wrestling is a distinction made to a professional wrestler who has won all of the major titles in a promotion. The Grand Slam typically consists of four titles, mirroring the grand slams found in golf and tennis. The four titles typically feature three tiers of heavyweight belts and a set of tag team belts. Because of this, a Grand Slam Champion is necessarily a Triple Crown Champion, which consists of the top two tiers of heavyweight belts and the tag team belts.

World Wrestling Federation / Entertainment
In the World Wrestling Federation (now known as "World Wrestling Entertainment") the term "Grand Slam Champion" was originally used by Shawn Michaels to describe himself upon winning the WWF Championship, the WWF Intercontinental Championship, the WWF European Championship and the WWF Tag Team Championship. As of 2007, only four wrestlers have held all four of those titles. As the European Championship was discontinued on July 22, 2002, the number of future potential Grand Slam Champions is limited to wrestlers who have already held the European Championship (see list of WWE European Champions).

In 2006, World Wrestling Entertainment stated, "Michaels was the first-ever Grand Slam Champion, capturing the European Championship once, the World Tag Team Championship four times, the Intercontinental Championship three times and the WWE and World Heavyweight Championships a total of four times." This indicates that WWE considers the World Heavyweight Championship to be an acceptable substitute for the WWF Championship (renamed the WWE Championship in 2002) in completing the Grand Slam. No wrestlers have completed the Grand Slam under this revised definition.

In April 2006, Kurt Angle was described as a "former Grand Slam Champion" on WWE.com, indicating that WWE considers the WWE Tag Team Championship to be an acceptable substitute for the World Tag Team Championship. Including Angle, two wrestlers have completed the Grand Slam under this revised definition.

Following WrestleMania 31 in 2015, WWE established a new version of the Grand Slam - consisting of the four currently active titles in WWE, which are the WWE World Heavyweight, Intercontinental, United States, and WWE Tag Team Championships. Eight wrestlers have been recognized as Grand Slam winners under these new parameters (including four who were already recognized as Grand Slam winners under the original guidelines). With the brand extension re-established, WWE indicated in 2017 that the WWE Universal Championship and the SmackDown Tag Team Championship are acceptable substitutes for their counterpart titles as part of the Grand Slam.

As of August 20 2017, 16 wrestlers have been recognized as WWE Grand Slam winners under its various incarnations.

Total Nonstop Action Wrestling
The first Total Nonstop Action Wrestling (TNA) Grand Slam champion 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. Styles defeated Booker T for the TNA Legends Championship. On the March 19 episode of TNA's primary television program, TNA Impact!, Impact! TV announcer Mike Tenay stated that Styles had become the first TNA Grand Slam champion by capturing the World Heavyweight (NWA or TNA), World Tag Team (NWA or TNA), TNA X Division, and TNA Legends/Global/Television Championships.
