The 2005 Six Nations Championship was the sixth Six Nations Championship played since the competition expanded in 2000 to include Italy. Including the Home Nations and Five Nations Championships, this was the 111th season of the tournament.
Wales won the Grand Slam, their first since 1978, and in doing so became the first team to win a Grand Slam playing more games away than at home.
