The New Zealand national rugby union team, commonly known as the All Blacks (Māori: Ōpango), represents New Zealand in men's international rugby, which is regarded as the country's national sport. Famous for their unparalleled international success, the All Blacks are often regarded as the most successful sports 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 hold the Rugby World Cup. New Zealand has a winning record of 76 per cent in test match rugby and has more wins than losses against any test opponent. Since their international debut in 1903, New Zealand teams have played exhibition games against 19 countries, 12 of which have never won a game against the All Blacks. The team has also played against three multinational all-star teams, losing just eight of 45 matches. 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 first-ranked country.
