Horseball is a game played on horseback where a ball is handled and points are scored by shooting it through a high net (approximately 1.5m×1.5m). The sport is like a combination of polo, rugby, and basketball. It is one of the ten disciplines officially recognized by the International Federation for Equestrian Sports.

The sport originated in Argentina in the early 1700s. It was outlawed in 1790 due to high mortality among players. In 1941 the Federacion Argentina de Pato was created. In 1953 was declared as Argentina's national game. The name of the game "pato" derives from the use of a live duck instead of the six-handled ball which is used in the modern sport. The game as its known today, including the use of a ball instead of an animal, was defined in the 1930s. It gained success and has spread across Europe and overseas. The International Horseball Federation has sixteen members including seven outside of Europe: Argentina, Brazil, Canada, Cayman Islands, Israel, Pakistan and the United States.
