1981 South Africa rugby union tour of New Zealand and the United States

The 1981 South African rugby tour (known in New Zealand as the 1981 Springbok Tour, and in South Africa as the Rebel Tour) polarised opinions and inspired widespread protests across New Zealand. The controversy also extended to the United States, where the South African rugby team continued their tour after departing New Zealand.

Apartheid had made South Africa an international pariah, and other countries were strongly discouraged from having sporting contacts with it. Rugby union was (and is) an extremely popular sport in New Zealand, and the South African national team, known as the Springboks, were considered to be New Zealand's most formidable opponents. Therefore, there was a major split in opinion in New Zealand as to whether politics should influence sport in this way and whether the Springboks should be allowed to tour.

The dispute was similar to that involving Peter Hain in the United Kingdom in the early 1970s, when Hain's Stop the Tour campaign clashed with the more conservative 'Freedom Under Law' movement championed by barrister Francis Bennion. The police response to the protests also became a focus of controversy. Although the protests were among the most intense in New Zealand's recent history, no deaths or serious injuries resulted.

After the tour, no official sporting contact took place between New Zealand and South Africa until the early 1990s, after apartheid had been abolished. The tour has been said to have led to a decline in the popularity of rugby union in New Zealand, until the 1987 Rugby World Cup.
