The National Football League (NFL) is a professional American football league consisting of 32 teams, divided equally between the National Football Conference (NFC) and the American Football Conference (AFC).

The NFL is one of the four major North American professional sports leagues and the highest professional level of American football in the world. Its eighteen-week regular season runs from early September to early January, with each team playing seventeen games and having one bye week.

Following the conclusion of the regular season, seven teams from each conference (four division winners and three wild card teams) advance to the playoffs, a single-elimination tournament culminating in the Super Bowl, which is usually held on the first Sunday in February and is played between the champions of the NFC and AFC. The league is headquartered in New York City.

The NFL was formed in 1920 as the American Professional Football Association (APFA) before renaming itself the National Football League for the 1922 season.
