The Crusaders (Māori: Whatumoana; formerly Canterbury Crusaders) are a New Zealand professional rugby union team based in Christchurch, who compete in the Super Rugby competition. They are the most successful team in the competition's history and have won a total of 13 titles (1998, 1999, 2000, 2002, 2005, 2006, 2008, 2017, 2018, 2019, 2022, 2023 and 2025) as well as two regionalised Super Rugby titles in 2020 and 2021.

Formed in 1996 to represent the upper South Island of New Zealand in the Super 12, the Crusaders represent the Buller, Canterbury, Mid-Canterbury, South Canterbury, Tasman and West Coast provincial Rugby Unions. Their main home ground since 2012 is Rugby League Park (known for sponsorship reasons as Apollo Projects Stadium). They formerly played out of Jade Stadium prior to it being damaged beyond repair in the 2011 Christchurch earthquake.

The Crusaders struggled in the first season of the Super 12, 1996, finishing last. Their performance improved in 1997 and the team finished sixth (out of twelve teams). The team went on to win three titles from 1998 to 2000 despite each final being played away from home. They again won the competition in 2002 after going through the season unbeaten. In the following two seasons, they again reached the final, although they were beaten on both occasions. In 2005, it was the last season of the Super 12 before its expansion. After finishing top of the table in that season, the Crusaders went on to host the final in which they defeated the Waratahs (35–25). As a result of winning their fifth Super 12 title, the Crusaders were given the trophy to keep. In 2006, the Crusaders hosted the Hurricanes in the inaugural Super 14 final and won (19–12). In 2008, the Crusaders hosted the final at AMI Stadium against the Waratahs, and won the match (20–12) to claim their seventh title. Their eighth championship came in the 2017 final when they defeated the Lions (25–17) in Johannesburg. The Crusaders hosted the Lions in the 2018 final and won (37–18), securing their ninth title. The Crusaders won their tenth Super Rugby title at home against the Jaguares (19–3) in the 2019 final. The Crusaders won their 11th and 12th title in both editions of Super Rugby Aotearoa in 2020 and 2021. They won their 11th full title (13th overall) by winning the inaugural Super Rugby Pacific final in 2022 against the Blues (21–7) at Eden Park in Auckland. The Crusaders won their 12th full Super Rugby title (14th overall) after beating the Chiefs (25–20) in the 2023 final in Hamilton. The Crusaders won their 13th full title (15th overall) after beating the Chiefs (16–12) in the 2025 final in Christchurch.

The Crusaders have been led by only three CEOs throughout their 29-year history; former New Zealand Rugby CEO Steve Tew, Hamish Riach and incumbent Colin Mansbridge.

The Crusaders franchise was created as one of five New Zealand teams in the Super 12. Originally named the Canterbury Crusaders, the Crusaders' franchise area encompassed the upper South Island of New Zealand (see Super Rugby franchise areas), and was formed from the Buller, Canterbury, Marlborough, Mid-Canterbury, Nelson Bays, South Canterbury, and West Coast rugby unions. The original Crusaders team of 1996 was captained by All Blacks prop Richard Loe and coached by Vance Stewart. The Crusaders struggled in the inaugural season and finished bottom of the table with only two wins. Their eight losses included a 49–18 loss to the Blues and a 52–16 loss to the Queensland Reds. And the First ever tour was a pre-visit to South Africa prior start of Super 12.

The following season saw a change in captain and coach, with Todd Blackadder succeeding Loe as captain and Wayne Smith taking over as coach. With five wins, the team finished the round-robin stage in sixth place. The improvement was particularly illustrated by the Crusaders' 29–28 loss to the defending champions, the Blues, which contrasted with their 49–18 loss the previous season. (The Blues also went on to win the 1997 title). During this loss, Leon MacDonald was taken out with a shoulder charge by Robin Brooke. While the Crusaders attempted to get MacDonald back on the field, the Blues scored two tries, including one by Brooke, who was later suspended for two weeks for the shoulder charge. In their last game of 1997, the Crusaders beat the Queensland Reds 48–3 at Lancaster Park.

The Crusaders won their first title in 1998, despite starting the season with three losses in their first four games. They finished the round-robin by winning their last seven games, culminating in a last-round win over the Coastal Sharks (now the Sharks) that gave them second place in the round-robin phase of the competition. Their second-placing allowed them to host their semi-final at Lancaster Park, where they won the match 36–32 against the Coastal Sharks.

In the final at Eden Park, the Crusaders faced the Blues, who were heavy favourites. According to Crusaders' hooker Mark Hammett, "If we'd been polled in that week, and had to give an honest answer, most of the boys, deep down, would probably have thought that the Blues would beat us." The Crusaders were ahead 3–0 at half time, but the Blues scored first after half time to take a 10–3 lead after 53 minutes. After Crusader Norm Maxwell scored a try, the game was tied 10 all. Then, after a penalty each, the two teams were tied 13 all with one minute of regulation time remaining. At that moment, Andrew Mehrtens chipped the ball for James Kerr to run onto and score, giving the Crusaders a 20–13 win after the try was converted. The ten points scored by Andrew Mehrtens in the final contributed to his total of 206 points for the season − a record for the Super 12. Upon the Crusaders' return to Christchurch, they were given a parade through the city that drew 100,000 people.
