Inoki Genome Federation (IGF) is a professional wrestling promotion in Japan founded by Antonio Inoki in 2007.

The IGF is now also the official National Wrestling Alliance (NWA) territory of Japan, since Antonio Inoki is the person who holds those rights and transferred them to IGF from New Japan Pro Wrestling.

Antonio Inoki left New Japan Pro Wrestling, a promotion he founded in 1972, to start the IGF. Inoki carried over to IGF his National Wrestling Alliance (NWA) accreditation, making IGF the official Japanese territory of the NWA.

In 2007, the IGF began a talent exchange with Total Nonstop Action Wrestling (TNA) of the United States, with Kurt Angle being the first TNA talent used by IGF.

The first IGF show was held on June 29, 2007 at the Sumo Hall in Tokyo, Japan. The card was completely changed at the last minute, resulting in the 8,426 fans in attendance not knowing who or what they were going to see outside of the main event of Kurt Angle vs. Brock Lesnar.

On February 22, 2010, IGF ran their 11th show since its inception.
