2025 Six Nations Championship

The 2025 Men's Six Nations Championship (known as the Guinness Men's Six Nations for sponsorship reasons and branded as M6N) was a rugby union competition that took place from late January to mid-March 2025, featuring the men's national teams of England, France, Ireland, Italy, Scotland and Wales. It was the 131st season of the competition (including its incarnations as the Home Nations Championship and the Five Nations Championship), but the 26th since it expanded to become the Six Nations Championship in 2000. It started on 31 January 2025 with a Friday night match between France and Wales, and ended with France against Scotland on 15 March. Ireland entered the tournament as two-time reigning champions, aiming to become the first team to win the Championship outright three years in a row. France returned to their normal home venue, the Stade de France in Saint-Denis, after a year away while the stadium was being prepared for the 2024 Summer Olympics.

France won the championship in the final match, crowned Six Nations champions for the seventh time, their 19th outright title in all formats and their 27th title overall. Three teams – France, England and holders Ireland – won four games and lost a fifth, with France triumphing on bonus points. Wales finished with a second successive Wooden Spoon after losing all five games. No team won the Grand Slam, although Ireland completed their 14th Triple Crown before defeat to France. Their third place finish was the worst of any Triple Crown-winning side; all previous winners had either won the championship or finished runners-up.
