The 2004 NFL season was the 85th regular season of the National Football League (NFL).

With the New England Patriots as the defending league champions, regular season play was held from September 9, 2004, to January 2, 2005. Hurricanes forced the rescheduling of two Miami Dolphins home games: the game against the Tennessee Titans was moved up one day to Saturday, September 11 to avoid oncoming Hurricane Ivan, while the game versus the Pittsburgh Steelers on Sunday, September 26 was moved back 7½ hours to miss the eye of Hurricane Jeanne.

The playoffs began on January 8, and eventually the New England Patriots repeated as NFL champions when they defeated the Philadelphia Eagles in Super Bowl XXXIX at ALLTEL Stadium in Jacksonville, Florida on February 6. It would mark the last time a team won back-to-back Super Bowls until 2023 (that team being the Kansas City Chiefs).

• February 24, 2004, The Washington Redskins released Bruce Smith, the NFL's all-time sack leader, saving $6.5 million in salary cap space.^[1]

The 2004 NFL draft was held from April 24 to 25, 2004 at New York City's Theater at Madison Square Garden. With the first pick, the San Diego Chargers selected quarterback Eli Manning from the University of Mississippi.

Ron Blum returned to line judge (where he officiated Super Bowl XXIV and Super Bowl XXVI), and Bill Vinovich was promoted to take his place as referee.

Midway through the season, Johnny Grier, the NFL's first African-American referee, suffered a leg injury that forced him to retire. He was permanently replaced by the back judge on his crew, Scott Green, who had previous experience as a referee in NFL Europe.

• Due to several incidents during the previous year, officials are authorized to penalize excessive celebration. The 15-yard unsportsmanlike conduct penalty will be marked off from the spot at the end of the previous play or, after a score, on the ensuing kickoff. If the infraction is ruled flagrant by the officials, the player(s) are ejected.
• Timeouts can be called by head coaches.
• The league's jersey numbering system was modified to allow wide receivers wear numbers 10–19, in addition to 80–89.
• A punt or missed field goal that is untouched by the receiving team is immediately dead once it touches either the end zone or any member of the kicking team in the end zone. Previously, a punt or missed field goal that lands in the end zone before being controlled by the kicking team could be picked up by a member of the receiving team and immediately run the other way.
• Teams will be awarded a third instant replay challenge if their first two are successful. Previously, teams were only limited to two regardless of what occurred during the game.
• The one-bar facemask was outlawed. The few remaining players who still used the one-bar facemask at the time were allowed to continue to use the style for the remainder of their career under a grandfather clause. (Scott Player was the last player to wear the one-bar facemask in 2007).

• Pat Tillman former safety for the Arizona Cardinals was killed during a friendly fire incident during the war in Afghanistan.
• Reggie White former defensive end for the Green Bay Packers, Philadelphia Eagles, and Carolina Panthers unexpectedly died on December 26, 2004, just seven days after his 43rd birthday from complications of sleep apnea.

Within each conference, the four division winners and the top two non-division winners with the best overall regular season records) qualified for the playoffs. The four division winners are seeded 1–4 based on their overall won-lost-tied record, and the wild card teams are seeded 5–6. 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 received a first-round bye. 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 met in the respective AFC and NFC Conference Championship games, hosted by the higher seed. Although the Super Bowl, the championship round of the playoffs, is played at a neutral site, the designated home team is based on an annual rotation by conference.^[3]

The Miami Dolphins were the first team to be eliminated from the playoff race, having reached a 1–9 record by week 11.^[4]

The following teams and players set all-time NFL records during the season:

The Colts led the NFL with 522 points scored. The Colts tallied more points in the first half of each of their games of the 2004 NFL season (277 points) than seven other NFL teams managed in the entire season.^[6] Despite throwing for 49 touchdown passes, Peyton Manning attempted fewer than 500 passes for the first time in his NFL career.^[7] The San Francisco 49ers' record 420 consecutive scoring games that had started in Week 5 of the 1977 season ended in Week 2 of the season.
