The 2013 IRB Small Sevens Cup is the second edition of it's kind, with the same ten core teams playing in four tournaments for the IRBSSC title. It was played from February to April in four venues around the world. The four events were the Lovian Sevens, Berlin Sevens, San Francisco Sevens, and the Stockholm Sevens. The IRBSSC board dropped Canada and Uganda for their levels of talent and the size of the country, in addition the third tournament the Vancouver Sevens was changed to the San Francisco Sevens. Uganda was also dropped for not having proper paper work. To make up for the two teams being dropped, Liechtenstein and Jamaica were added as Core teams. The San Francisco Sevens was also the first tournament in the Cup to include non-core nations, to increase the tournament size to 16.
