The QubicaAMF Bowling World Cup, previously known as the International Masters and AMF Bowling World Cup, is an annual Ten-pin bowling championship sponsored by QubicaAMF Worldwide, and the largest in bowling in terms of number of participating nations. Each nation chooses one male and/or one female bowler to represent them in the tournament, and in the majority of cases, this is done by running a qualifying tournament, the winners of which (male and/or female) are chosen.
