The Women's Six Nations Championship, known as the TikTok Women's Six Nations for sponsorship purposes, is an international rugby union competition contested between six European women's national teams. It started in the 1995–96 season as the Home Nations, with four teams: England, Ireland, Scotland and Wales. In the 1998–99 season it became the Five Nations, with France joining the original four. The following season, Spain replaced Ireland for two seasons. England have been the dominant team in the competition, winning 18 of 27 editions entering 2022. France is next with six titles.
