The National Gridiron League (NGL) is an American professional football league. It is composed of 12 teams based throughout the United States southeast and mid-west states. The NGL is one of the six major professional sports leagues in North America.

Established in October of 2017, the NGL is America's premier spring football league with an annual kickoff set for March of each calendar year.

The league's inaugural season of competition was initially set for the spring of 2020, but health concerns created by COVID-19 derailed those plans. The kickoff season has been adjusted for March of 2021, with 12 teams set to compete in the inaugural season.

The NGL will crown its first league champion franchise in August of 2021 with two teams (one from the NGL's eastern conference and one from the NGL's western conference) competing in an annually held championship game named the "Gridiron Classic." The annual event will be hosted at a prearranged neutral site venue in August of each calendar year.

The National Gridiron League is headquartered in Atlanta, Georgia.
