The New Zealand national rugby union team, known as the All Blacks (Māori: Ōpango), represents New Zealand in international men's rugby, which is considered the country's national sport. Famous for their unparalleled international success, the All Blacks are often regarded as the most successful sporting team in history.

The team won the Rugby World Cup in 1987, 2011 and 2015. They were the first country to win the Rugby World Cup 3 times and the first country to retain the Rugby World Cup. New Zealand has a 76 percent winning record in test match rugby and has recorded more wins than losses against any test opponent. Since their international debut in 1903, New Zealand teams have played test matches against 19 countries, 12 of which have never won a match against the All Blacks. The team has also played against three multinational all-star teams and lost only eight of 45 games. Since the introduction of the World Rugby Rankings in 2003, New Zealand has been number one for longer than all other teams combined. Together with England, they jointly hold the record for most consecutive Test match wins for a top-tier country.
