The 2004 Six Nations Championship was the fifth series of the rugby union Six Nations Championship to be held since the competition expanded in 2000 to include Italy. Overall, this was the 110th series of the international championship.
Match winners received two points, with one for a draw and none for a loss. The first tiebreaker was points difference.
France won the competition, also winning the Grand Slam. Ireland won the Triple Crown, sweeping their matches against Wales, England and Scotland. Scotland were whitewashed, earning the wooden spoon as a result.
