European Rugby Champions Cup

The European Rugby Champions Cup (known as the Investec Champions Cup for sponsorship reasons) is an annual rugby union tournament organised by European Professional Club Rugby (EPCR). It is the top-tier competition for clubs who compete in a predominantly European league. Clubs qualify for the Champions Cup via their final positions in their respective national/regional leagues (English Premiership, French Top 14, and United Rugby Championship) or via winning the second-tier Challenge Cup; those that do not qualify are instead eligible to compete in the second-tier Challenge Cup.

Between 1995 and 2014, the equivalent competition was known as the Heineken Cup and was run by European Rugby Cup. Following disagreements between its shareholders over the structure and governance of the competition, it was taken over by EPCR and its name was changed to the European Rugby Champions Cup, without title sponsorship. Heineken returned as sponsor for the 2018–19 season, resulting in the competition being known as the Heineken Champions Cup. Although they are technically two separate competitions, run by different organisations, the European Rugby Cup and the European Rugby Champions Cup are recognised as one title chain of elite club championships in Europe, with teams that have won multiple titles ranked, for example, by the aggregate of their wins in both versions.

French clubs have the highest number of victories (13 wins), followed by England (10 wins) and Ireland (7 wins). England has the largest number of winning teams, with six clubs having won the title. The competition has been won by thirteen different clubs, eight of which have won it more than once, and five successfully defended their title including a unique three-in-a-row made by Toulon between 2012–13 and 2014–15. Toulouse is the most successful club in the tournament's history, having won it 6 times, including the first season of the tournament in the 1995–96 season. Bordeaux are the current European champions, having beaten Northampton Saints 28–20 in the 2025 final in Cardiff, Wales. Toulouse have completed "the Double" (Heineken Cup/European Rugby Champions Cup-National Championship) 3 times (1995–96, 2020–21 and 2023–24), a record in Europe.

The Heineken Cup was launched in the summer of 1995 on the initiative of the then Five Nations Committee to provide a new level of professional cross border competition. Twelve sides representing Ireland, Wales, Italy, Romania and France competed in four pools of three with the group winners going directly into the semi-finals. English and Scottish teams did not take part in the inaugural competition. From an inauspicious beginning in Romania, where Toulouse defeated Farul Constanţa 54–10 in front of a small crowd, the competition gathered momentum and crowds grew. Toulouse went on to become the first European cup winners, eventually beating Cardiff in extra time in front of a crowd of 21,800 at Cardiff Arms Park.

Clubs from England and Scotland joined the competition in 1996–97. European rugby was further expanded with the advent of the European Challenge Cup for teams that did not qualify for the Heineken Cup. The Heineken Cup now had 20 teams divided into four pools of five. Only Leicester and Brive reached the knock-out stages with 100 per cent records and ultimately made it to the final, Cardiff and Toulouse falling in the semi-finals. After 46 matches, Brive beat Leicester 28–9 in front of a crowd of 41,664 at Cardiff Arms Park, the match watched by an estimated television audience of 35 million in 86 countries.

The season 1997–98 saw the introduction of a home and away format in the pool games. The five pools of four teams, which guaranteed each team a minimum of six games, and the three quarter-final play-off matches all added up to a 70-match tournament. Brive reached the final again but were beaten late in the game by Bath with a penalty kick. Ironically, English clubs had decided to withdraw from the competition in a dispute over the way it was run.

Without English clubs, the 1998–99 tournament revolved around France, Italy and the Celtic nations. Sixteen teams took part in four pools of four. French clubs filled the top positions in three of the groups and for the fourth consecutive year a French club, in the shape of Colomiers from the Toulouse suburbs, reached the final. Despite this it was to be Ulster's year as they beat Toulouse (twice) and reigning French champions Stade Français on their way to the final at Lansdowne Road, Dublin. Ulster then carried home the trophy after a 21–6 win over Colomiers in front of a capacity 49,000 crowd.

English clubs returned in 1999–00. The pool stages were spread over three months to allow the competition to develop alongside the nations' own domestic competitions, and the knockout stages were scheduled to take the tournament into the early spring. For the first time clubs from four nations – England, Ireland, France and Wales – made it through to the semi-finals. Munster's defeat of Toulouse in Bordeaux ended France's record of having contested every final and Northampton Saints' victory over Llanelli made them the third English club to make it to the final. The competition was decided with a final between Munster and Northampton, with Northampton coming out on top by a single point to claim their first major honour.
