Fantasy hockey is a form of fantasy sport where players build a team that competes with other players who do the same, based on the statistics generated by professional hockey players or teams. The majority of fantasy hockey pools are based on the teams and players of the National Hockey League (NHL).

A typical fantasy hockey league or hockey pool has 8 - 12 teams but often have as many as 20. Other types of pools may have a greater number of teams, which may dilute the average talent making it more or less fun depending on the league, but also represents more closely the actual NHL, which currently has 30 teams. Other forms of fantasy hockey may allow an unlimited number of teams, whereby any number of owners may draft the same player(s). These typically have a restricted number of "trades" where one player may simply be exchanged for any other in the player pool, typically of the same position
