2011 Women's Six Nations Championship

The 2011 Women's Six Nations Championship, also known as the 2011 RBS Women's 6 Nations due to the tournament's sponsorship by the Royal Bank of Scotland, was the tenth series of the Women's Six Nations Championship, an annual women's rugby union competition between six European rugby union national teams. Matches were held between 4 February and 19 March 2011, on the same weekends as the men's tournament, if not always the same day. The game between England and Scotland on 13 March followed the men's international between the same two nations and was shown live on the BBC. The match between England and France was also shown live on Sky TV in the UK, and France vs Scotland was broadcast live on Orange TV in France.

The championship was contested by England, France, Ireland, Italy, Scotland and Wales. England were favourites to win the tournament, and their victory was their sixth title in a row. Italy also had their best Six Nations ever. Scotland, on the other hand, lost every match (other than their game against Ireland) by record margins.
