The 2001 NFL season was the 82nd regular season of the National Football League (NFL), and the first season of the 21st century. The league permanently moved the first week of the regular season to the weekend following Labor Day. In the wake of the September 11 attacks, the NFL's week 2 games (September 16 and 17) were postponed and rescheduled to the weekend of January 6 and 7, 2002. To retain the full playoff format, all playoff games, including Super Bowl XXXVI, were rescheduled one week later. The New England Patriots won the Super Bowl, defeating the St. Louis Rams 20–17 at the Louisiana Superdome.
This is the last season with 31 teams as the Houston Texans were introduced as an expansion team the following season.
