The 2015 World Club Series was the inaugural World Club Series and was contested by six clubs (three each from the Super League and National Rugby League), including Super League XIX champions, St Helens R.F.C. and 2014 NRL Premiers, the South Sydney Rabbitohs. The 2015 series marked a departure from the previous format, whereby only the premiers from the two respective competitions would take part.
