2004 Kansas City Chiefs season

The 2004 Kansas City Chiefs season was the franchise's 45th season, their 42nd in Kansas City, and 35th in the National Football League.

The 2004 season proved not to be as successful as the team's previous season. Though the Chiefs finished the regular season with the most yards and the second highest number of points, they also had a losing record of 7–9 and no playoff appearance. In fact, the Chiefs' 483 points-scored was the highest total in NFL history for a team that finished the season with a losing record. The Chiefs joined the 1975 Buffalo Bills as the only teams in NFL history to score an average of at least 30 points per game and miss the playoffs.
