Unicycle hockey is a team sport, similar to roller or inline hockey, except that each player must be mounted on a unicycle to play the ball. A team is composed of five players (plus substitutes), but there is no dedicated goalkeeper role (although one player usually stays back in that position).
The governing body for unicycle hockey is the International Unicycling Federation which publishes the rules for all unicycle sports. The most recent set of rules for unicycle hockey was published in 2015.
The court used is between 35 and 45 metres in length, and 20 to 25 metres wide. It should have either beveled or rounded corners, and barriers on all sides. The goals are also set back from the end walls so that players can go behind them, similarly to ice hockey.
Any stick which is legal for ice hockey, other than that of a goalkeeper, can be used. The unicycles can have a maximum wheel diameter of 24 inches (61 cm) and a tennis ball is used.
In 1960, unicycle hockey was mentioned as one of the activities of the Albuquerque Unicycle Club, founded in 1957, and then the only known unicycle club in the United States. In 1971, the game was being played in Japan.
In 1976, a unicycle hockey club called 'Wheel People' was founded in California and ran for about ten years. In 1985, LaHiMo became the first German unicycle hockey club, based in Langenfeld. The sport spread to the UK, with a national competition in 1988 at Covent Garden in London. In 1990, Jens Stemminger founded the Uniwheelers in Bremen. Radlos was the third German club, in Frankfurt from 1991, and others soon followed, leading to the foundation of the German league, still the world's largest. 
In the early 1990s, the sport was introduced to Switzerland by Jojo Mühlmeyer, a Lahimo/Radlos pioneer.
The following year, the first unicycle hockey world championships took place at Unicon VII in Minneapolis, in the United States, won by Germany. Every Unicon since has included a hockey championships. The current world champions, from Unicon XIX in Ansan, Korea, are Swiss Team.
