TNA World Championship

The TNA World Championship is a professional wrestling world championship created and promoted by Total Nonstop Action Wrestling (TNA). It is the promotion's principal championship. Like most professional wrestling championships, the title is won via pinfall or submission. The reigning champion is Trick Williams from partner promotion WWE, who is in his first reign and is the first WWE-contracted wrestler to hold a TNA title. He won the championship by defeating Joe Hendry at NXT Battleground on May 25, 2025.

Before the championship was created, TNA controlled the NWA World Heavyweight Championship via an agreement with the National Wrestling Alliance (NWA). In 2007, the agreement between TNA and the NWA ended, leading to the creation of the TNA World Heavyweight Championship. The championship was unveiled on May 14, 2007, at the taping of TNA's primary television program, Impact!, which aired on May 17, 2007. The inaugural champion was Kurt Angle, who also holds the record for the most reigns at six.

When TNA changed its name and became Impact Wrestling in March 2017, the title was renamed soon after to reflect the change. After Impact Wrestling rebranded to Global Force Wrestling (GFW) later that year, the title was unified with the original GFW Global Championship at Slammiversary XV and became the Unified GFW World Heavyweight Championship. Following Destination X, the title took the GFW Global Championship name and kept the former TNA lineage. On October 23, 2017, the GFW name was dropped, and the company name reverted to Impact Wrestling when the company severed ties with Jeff Jarrett, and he took the GFW name with him. However, Impact Wrestling kept the Global Championship name for their championship and the title was then called the Impact Global Championship. On the February 1, 2018, episode of Impact!, the title became known as the Impact World Championship. On June 4, 2018, the title was unified with the Impact Grand Championship and on March 13, 2021, it was unified with the TNA World Heavyweight Championship, which was briefly sanctioned in 2021 as a separate title from the Impact World Championship. In January 2024, Impact Wrestling reverted back to the TNA name, thus renaming the title as TNA World Championship.
