The World Polo Championship is a polo competition between countries. The event is organised by the sport's governing body, the Federation of International Polo (FIP), and is contested by the national teams. There is no restriction on the gender of the players. The inaugural tournament was held in 1987, hosted by Argentina, and is now contested every three or four years.

Polo is a ball game that is played on horseback, a traditional field sport and one of the world's oldest known team sports. The game is played by two opposing teams with the objective of scoring using a long-handled wooden mallet to hit a small hard ball through the opposing team's goal. Each team has four mounted riders, and the game usually lasts one to two hours, divided into periods called chukkas or chukkers.
