History
The Amateur Athletic Union (AAU) was the official organization responsible for the running of all amateur sports in the United States, established in 1888. The AAU was officially charged with the organization and operation of many sports in the US. During this time, Karate was one of the committees in the organization and was not an independent governing body.

The Amateur Sports Act of 1978 enabled the governance of sports in the U.S. by organizations other than the AAU. This act made each sport set up its own National governing body (NGB). Each of these governing bodies would be part of the United States Olympic & Paralympic Committee, but would not be run by the committee. Thus, The USA Karate Federation was born.

USA National Karate-do Federation is the latest of previous organizations to claim to represent Karate in the United States. USA National Karate-do Federation replaces USA Karate Federation.

On April 24, 2021, the USOPC sent a demand letter to the USA-NKF for immediate reform and adoption of accountability measures. An investigation ordered by the USOPC found numerous actual and perceived conflicts of interest which show bias in favor of certain dojos' athletes. The USOPC has warned the USA-NKF their NGB status could be revoked if they fail to implement reforms.
