Horseball is a sport played on horseback where a ball is handled and goals are scored by shooting it through a hoop with a diameter of 1m. The sport is a combination of polo, rugby, netball, and basketball. It is one of the ten disciplines officially recognized by the International Federation for Equestrian Sports (FEI); in 2015 the International Horseball Federation [fr] (FIHB) and the International University Sports Federation (FISU) signed memorandums of understanding with the FEI.

Horseball was invented by Captain Clave of the French Army, a show jumping world champion. The ball and the basis of the Goals was borrowed from Pato, the Argentine national sport but there the similarity ends. The game was designed to improve partnerships between horses and riders, that could be played on a standard equestrian arena, and would be fun to play. It was developed by a French group under the presidency of Jean Paul Depons, a riding instructor and rugby player from Bordeaux. This group established the rules of horseball in France.

In the late 1970s, the French Equestrian Federation (FFE) accepted horseball as a discipline and it soon became popular in France. Horseball spread internationally in the early 1990s. In 1992 the International Commission of Horseball was established, with France, Belgium, Germany, Great Britain, Italy, and Portugal as members. The first European Cup was held in Paris in December 1992, at the Salon De Cheval.

Another source of inspiration for horse-ball is an ancient Afghan equestrian sport, Buzkashi.

Horseball is an equestrian sport that is like a combination of rugby and basketball, played on horseback. It is a fast-paced team game, with the objective of scoring goals. Each team has four players, and two substitutes. Teams must make at least three passes between different players before scoring. Players can be substituted at any break of play. The ball is a football held in a harness with six handles, so that it can be picked up. Players may hold the ball for less than 10 seconds, and must pass the ball when making an attack. If the ball falls to the ground, players may only pick it up without changing pace, or dismounting. This is called "ramassage". Players score by throwing the ball through a goal. This is a 1-metre diameter vertical hoop at the end of the pitch, suspended 3.5 metres from the ground and hung 1-metre into the pitch. The game is usually played on a rectangular pitch, with dimensions of 65 meters by 25 meters. Games last 20 minutes, in two 10-minute halves, and with a 3-minute half-time break when the teams change ends. The team that scores the most goals win.

The International Horseball Federation [fr] (FIHB) was formed in 1999.

In 1992 the International Commission of Horseball was established, with France, Belgium, Germany, Great Britain, Italy, and Portugal as members. The first European Cup was held in Paris in December 1992, at the Salon De Cheval.

Recognized by the International Equestrian Federation (FEI) since 2015, it has been chaired by Frederico Cannas since its creation.
