1980 South American Jaguars rugby union tour of South Africa

The 1980 Sudamérica XV rugby union tour of South Africa was a series of seven matches played by the Sudamérica XV (also named the Jaguars) rugby union team in South Africa in April and May 1980. The South American team won five of the matches but lost both that were against the South Africa national team.

The touring party was composed almost entirely of players from the Argentina national rugby union team and included all but one of the players who had played for Argentina in a drawn series with Australia in 1979. The touring party numbered twenty-six players, of whom one came from Brazil, one from Chile, one from Uruguay and one from Paraguay. The other twenty-two players came from Argentina, including the captain, Hugo Porta. Porta was asked to return to South Africa later that year to play for the South African Barbarians against the touring 1980 British Lions.

The players were individually invited to play in this tour and against South Africa in two matches played later during the Springboks tour of South America.

The "South America Jaguars" was a "ghost" Argentine national team, not officially recognised by Argentine Rugby Union, to elude the Argentine government prohibition that since the early 1970s had forbid any official relationship between any Argentine sport federation and South African and Rhodesian ones due to the apartheid politics of the two African countries. This started in 1971 when the Argentine government forbid the national team from playing a match in Rhodesia during the tour in South Africa. Later in 1973, after a controversial period, the government forbid any sport relationship with South Africa.
