The ICS Ioroball Cup is the premier Ioroball tournament in the sport. It has been held every two years since 15 AKR, with a number of exceptions, such as the 19 ICS Ioroball Cup, which was cancelled because of the Catastrophe of the Star. The location of the Cup changes every time with the ICS Cup Commission picking the location four years prior to the event. Crelina, as the origin of the sport, has held the Cup the most times with 479.
