The five biggest rivalries in the Six Nations (Ranked 5-1)

These are the fixtures supporters circle first, where history weighs heavy and every result is remembered. We look back at the matchups that define the championship and why they still matter so deeply to players and fans alike.

The rivalry between Ireland and Scotland brings a distinctive edge to the Six Nations, intensified by the Centenary Quaich, awarded to the winner of their annual meeting. Steeped in tradition and shared rugby heritage, these encounters are renowned for their physicality and drama, often leaving a lasting impression on the championship.

Historically, control of the Quaich has swung between the two nations. Scotland dominated the early years, holding the trophy for eleven seasons, including a drawn match that allowed them to retain it. Since 2000, however, Ireland have been the prevailing force, winning 22 of the last 26 contests.

Ireland are the current holders, having secured an eighth consecutive victory over Scotland at Murrayfield on 9 February 2025.

One of rugby’s most famous rivalries, England versus France—known as Le Crunch—is defined by history, passion, and unpredictability. First contested in 1906, the fixture reflects not only sporting rivalry but also deep-rooted cultural and historical tensions between the two nations.

These matches are often marked by flair, physicality, and sudden momentum shifts, making them a perennial highlight of the Six Nations. Beyond their annual championship clash, the sides have met in six World Cup warm-up matches ahead of the 2003, 2007, and 2015 tournaments, with France winning four and England two. At the Rugby World Cup itself, they have faced each other five times, with England winning three encounters and France two.

Ireland and Wales share one of the most compelling rivalries in rugby, shaped by common Celtic roots and a tradition of open, attacking play. Their annual battle for the Millennium Trophy adds extra significance, ensuring each encounter is fiercely contested and emotionally charged.

The two nations first met in 1882 and have played 136 times, with Wales winning 70 matches, Ireland 59, and seven ending in draws. On the World Cup stage, they have faced each other three times: Wales won in 1987 and 2011, while Ireland eliminated Wales in 1995.

Few trophies in world rugby carry the prestige of the Calcutta Cup, contested annually by Scotland and England since 1879. As the oldest international rugby trophy—predating the Bledisloe Cup by over fifty years—it symbolizes more than just victory: it represents pride, history, and bragging rights.

Matches for the Cup are typically defined by intensity, tactical battles, and dramatic swings in momentum. As the oldest of several trophies contested within the Six Nations framework, the Calcutta Cup remains one of the championship’s most anticipated fixtures.

At the pinnacle of Six Nations rivalries stands Wales versus England—a fixture steeped in history, proximity, and fierce national pride. Encounters between these two rugby giants are renowned for their passion, iconic moments, and uncompromising physicality. The added incentive of the Triple Crown, awarded to the top Home Nation, often raises the stakes even higher.

The rivalry dates back to 1881, with the teams having played 143 matches: England have won 70, Wales 61, and 12 have ended in draws. Their geographic closeness and long-shared history only deepen the intensity of this contest.
