The 2003 Six Nations Championship was the fourth series of the rugby union Six Nations Championship, and the 109th international championship overall. The annual tournament was won by England, who completed a grand slam, and went on to win the 2003 Rugby World Cup later the same year. Italy won their first match with Wales (30–22), finishing in 6th place for the first time in the process.
This was the sixth time in the Championship's history, but the first time since it became the Six Nations, that two teams met in the final round with undefeated records, both England and Ireland having won their first four games, making the final match a decider for the Grand Slam. It was also the first time Ireland had been involved: and the first that was won by the away team. Wales were whitewashed, losing all five of their games, and earned themselves the wooden spoon as a result.
