2013 IRB Junior World Championship

The 2013 IRB Junior World Championship was the sixth, IRB Junior World Championship, an annual international rugby union competition for Under 20 national teams. The event was organised in France by rugby's governing body, the IRB. A total of twelve nations played in the tournament. South Africa went into the tournament as defending champions, after winning the tournament for the first time in 2012. England were crowned the 2013 champions for the first time after defeating Wales 23–15 in the final on the 23 June at Stade de la Rabine in Vannes.

After finishing last at the 2012 IRB Junior World Championship, Italy were relegated to the IRB Junior World Trophy and therefore didn't participate in this year's event. After finishing first at the 2012 IRB Junior World Rugby Trophy, the United States were promoted to this competition for 2013. Their stay in the IRB Junior World Championship was short-lived, however, as they lost in the 11th-place final to Fiji 46–12 and were relegated to the IRB Junior World Trophy, being replaced for the 2014 competition by its winners Italy.
