2006 Wales rugby union tour of Argentina

In June 2006, the Wales national rugby union team travelled to Argentina for a two-test series against the Argentina national team. The first test was played on 11 June in Puerto Madryn, a city in the heart of the former Welsh colony in Patagonia, founded by Welsh settlers in 1865. The second test was played in Buenos Aires a week later. They were Wales' first matches under the management of new head coach Gareth Jenkins, who had been appointed to replace Mike Ruddock in April 2006. The test series was thrown into doubt earlier in the year after 60 Argentine players threatened to retire from international duty due to a dispute with the Argentine Rugby Union (UAR), but this was resolved at the end of May 2006. Argentina won both tests, claiming a 27–25 victory in Puerto Madryn before a more convincing 45–27 win in Buenos Aires.
