Geography of water polo

Water polo is a full-contact sport played in many countries around the world. The sport's international governing body is FINA.

Some countries have two principal competitions: a more prestigious league which is typically a double round-robin tournament restricted to the elite clubs, and a cup which is a single-elimination tournament open to both the elite and lesser clubs.
