The 2000 Six Nations Championship was the first series of the rugby union Six Nations Championship, following the addition of Italy to the Five Nations. It was the 106th season of the championship overall.
The title was won by England. England won their first four games and met winless Scotland in their final match. Scotland earned a surprising victory and denied England the Grand Slam.
Italy won their first game in the championship with a surprising 34–20 win over Scotland, who had won the previous year's Five Nations. Italy did not win any of their other games and finished in sixth place.[1]
