The TNA Knockouts World Tag Team Championship is a women's professional wrestling tag team championship owned by the professional wrestling promotion Total Nonstop Action Wrestling (TNA). It is contested for mainly by teams consisting of two female wrestlers in TNA, known as the TNA Knockouts; however, the championship was once held by a male. The current champions are The IInspiration (Jessie McKay and Cassie Lee), who are in their second reign as a team and individually. They won the titles by defeating The Elegance Brand (Heather by Elegance and M by Elegance) at TNA iMPACT! on October 2, 2025 in Edmonton, Alberta, Canada.

The creation of the championship was announced on August 20, 2009, during a backstage segment on TNA's primary television program TNA Impact!. Like most professional wrestling championships, the title is won via the result of a scripted match. Sarita and Taylor Wilde were the inaugural champions. They won a four-week tournament to be crowned the first champions. The longest reigning champions were Eric Young and ODB, who held the titles for a record 478 days before the 2013 deactivation of the titles due to Eric Young being a male talent.

On October 24, 2020, at Bound For Glory, the revival of the titles were officially announced by Madison Rayne, with a tournament to award the revived championships taking place. On January 16, 2021, the tournament finals were won by Fire 'N Flava (Kiera Hogan and Tasha Steelz) at Hard To Kill.

TNA Knockout (formerly Impact Knockout), or just Knockout for short, is the term used by TNA's Total Nonstop Action Wrestling (formerly Impact Wrestling) to refer to its onscreen female employees; this is similar to World Wrestling Entertainment and the Divas pseudonym they then used. In October 2007 at TNA's Bound for Glory PPV event, TNA established their first women's championship, with Gail Kim winning a 10 knockout gauntlet match to become the first TNA Women's Knockout Champion.

On the August 20, 2009 episode of Impact!, backstage interviewer Lauren, who was standing with and about to interview Christy Hemme, Tara, Taylor Wilde, and Sarita, announced that TNA were planning to host an eight-team single elimination tag team tournament to crown the first-ever TNA Knockouts Tag Team Champions. After a four-way match consisting of Hemme, Traci Brooks, Sarita, and Awesome Kong, TNA commentators Mike Tenay and Taz announced that the tournament would begin on the August 27 episode of Impact!. The first champions were crowned at No Surrender, where Sarita and Taylor Wilde defeated The Beautiful People.

During the first years of the title, it was vacated twice due to one half of the champions being released. On March 8, 2010, Awesome Kong left TNA after an incident with Bubba the Love Sponge. In December of that year, Hamada was released. On February 28, 2011, ODB and Eric Young defeated Gail Kim and Madison Rayne to win the titles. Young also became the only male to win the championship. They only defended the titles two times, but held the belts for 478 days. On the June 20, 2013 episode of Impact Wrestling, Knockouts Division Executive Brooke Hogan stripped ODB and Young of the title because Young is a male. This ultimately resulted in the titles being deactivated.

On October 24, 2020 at the Bound for Glory pay-per-view, Madison Rayne announced that after nearly eight years of inactivity, Impact Wrestling would revive the Knockouts Tag Team Championship. It was also announced that an eight-team tournament would take place over the next two months to determine the next champions. The brackets were announced in November, with the final taking place at the Hard To Kill pay-per-view on January 16, 2021. At the event, Fire 'N Flava (Kiera Hogan and Tasha Steelz) defeated Havok and Nevaeh in the tournament final to win the revived titles.
