The 2002 FINA Men's Water Polo World Cup was the twelfth edition of the event, organised by the world's governing body in aquatics, the International Swimming Federation (FINA).

The event took place in the Tašmajdan Swimming Pool in Belgrade, Yugoslavia from August 20 to August 25, 2002.

The FINA Cup in Belgrade decided which teams qualified directly to the 2003 World Aquatics Championships in Barcelona, Spain from July 13 to July 27, 2003.

Russia and Hungary, as well as the host Spain, already qualified based on the results from the 2002 FINA Men's Water Polo World League (June 28 – August 4, 2002).

The top eight teams from the previous World Aquatic Championship have qualified.
