Regular-season play was held from September 4, 2003, to December 28, 2003. Due to damage caused by the Cedar Fire, Qualcomm Stadium was used as an emergency shelter, and thus the Miami Dolphins–San Diego Chargers regular-season match on October 27 was instead played at Sun Devil Stadium, the home field of the Arizona Cardinals.
The playoffs began on January 3, 2004. The NFL title was won by the New England Patriots when they defeated the Carolina Panthers, 32–29, in Super Bowl XXXVIII at Reliant Stadium in Houston, Texas, on February 1.
This was the last season until the 2016 NFL season where neither of the previous Super Bowl participants made the playoffs.

Major rule changes
- If an onside kick inside the final five minutes of the game does not go 10 yards, goes out of bounds, or is touched illegally, the receiving team will have the option of accepting the penalty and getting the ball immediately. Previously, the kicking team was penalized, but had another chance to kick again from five yards back.
- League officials encouraged networks to immediately cut to a commercial break if an instant replay challenge review was initiated. Previously networks were generally not permitted to utilize those game stoppages for their prescribed commercial periods.

Within each conference, the four division winners and the two wild card teams (the top two non-division winners with the best overall regular season records) qualified for the playoffs. The four division winners are seeded 1 through 4 based on their overall won-lost-tied record, and the wild card teams are seeded 5 and 6. The NFL does not use a fixed bracket playoff system, and there are no restrictions regarding teams from the same division matching up in any round. In the first round, dubbed the wild-card playoffs or wild-card weekend, the third-seeded division winner hosts the sixth seed wild card, and the fourth seed hosts the fifth. The 1 and 2 seeds from each conference then receive a bye in the first round. In the second round, the divisional playoffs, the number 1 seed hosts the worst surviving seed from the first round (seed 4, 5 or 6), while the number 2 seed will play the other team (seed 3, 4 or 5). The two surviving teams from each conference's divisional playoff games then meet in the respective AFC and NFC Conference Championship games, hosted by the higher seed. Although the Super Bowl, the fourth and final round of the playoffs, is played at a neutral site, the designated home team is based on an annual rotation by conference.
