The IRB 2015 Rugby World Cup was the eighth Rugby World Cup, the quadrennial rugby union world championship. The tournament was hosted by England from 18 September to 31 October. Of the 20 countries competing in the World Cup in 2011, there was only one change: Uruguay replaced Russia. This was the first World Cup with no new teams to the tournament.

Reigning champions New Zealand won the cup and defended their title by defeating Australia 34–17 in the final; South Africa defeated Argentina to take third place. This was the first Rugby World Cup where no Northern Hemisphere team got beyond the quarter-finals. New Zealand were the first team to retain their title and the first to win for a third time.

2015 Rugby World Cup

The highly contested match between Japan and South Africa on the opening weekend, in which Japan scored the winning try in the final minute, was widely considered the biggest upset in the history of rugby. Hosts England were eliminated at the pool stage, after defeats by Wales and Australia; this was the first time the knockout stage did not feature a host nation.

Host selection

Submission of interest

The International Rugby Board (IRB) requested that any member unions wishing to host this tournament or the 2019 Rugby World Cup should indicate their interest by 15 August 2008. This would be purely to indicate interest; no details had to be provided at this stage. A record 10 unions indicated formal interest in hosting the 2015 and/or the 2019 events: Australia, England, Ireland, Italy, Jamaica, Japan, Russia, Scotland, South Africa and Wales. Argentina had been reported in early 2008 as having given preliminary consideration to bidding, but did not ultimately formally indicate an interest in bidding.

2015 Rugby World Cup

Of the 10 nations that had expressed formal interest, many withdrew their candidacy in early 2009. Jamaica was the first to withdraw its candidacy. Russia withdrew in February 2009 to concentrate on bidding for the 2013 Rugby World Cup Sevens, Australia and Ireland withdrew in spring 2009 due to financial reasons. Scotland withdrew in April 2009 after they were unable to secure co-hosting partners for the tournament. Wales was the last nation to officially pull out after they failed to submit a bid by 8 May 2009, but Wales backed England's bid and some games were played at Cardiff's Millennium Stadium.

Final bids

The final nations that bid for the right to host the 2015 Rugby World Cup were England, Japan, South Africa and Italy. Four confirmed bids was a record number for the Rugby World Cup.

On 28 July 2009, the IRB confirmed that England would host the 2015 Rugby World Cup, and Japan would host the 2019 event, having voted 16–10 in favour of approving the recommendation from Rugby World Cup Ltd (RWCL) that England and Japan should be named hosts. RWCL chairman Bernard Lapasset revealed the result on 28 July 2009 at IRB headquarters.

England

In September 2007, The Guardian reported that the Rugby Football Union had decided to submit a bid. BBC News reported in February 2009 that the intent was for a solo bid from the RFU, but with the possibility of some matches being played in Scotland, Wales or Ireland. It was hoped that the 2015 World Cup would add to Britain's "Decade of Sport" (including the 2012 Summer Olympics, 2013 Rugby League World Cup and 2014 Commonwealth Games).

It was also claimed that the bid had a very strong chance of success due to the IRB's belief that the 2011 tournament might make a loss, therefore making it particularly important to ensure a profit, which was considered a strong point of England's proposed bid. The chief executive of the Rugby Football Union, Francis Baron, said that the tournament would target sales of 3 million tickets. England's package was projected to generate £300 million for the IRB – £220 million in commercial returns from broadcasting, sponsorship and merchandising, and the £80 million tournament fee.

Italy

Italy stated its desire to host, and an Italian bid to host the Rugby World Cup in 2015 or 2019 was confirmed on 20 July 2008. Italy declared that it wanted to host "For the Enlargement of the Frontiers of Our Sport". It was a slogan relevant to the then-current landscape of World Cup rugby, given that 2007 was the first time that the Rugby World Cup was hosted by a primarily non-English-speaking country.
