Inline hockey, often referred to as roller hockey in the United States, is a sport similar to ice hockey but played with inline skates. Like its parent sport, skaters on two teams use hockey sticks to direct a disk-shaped puck into the opponent's goal; however, various details of the game, such as the playing surface and puck design, have been adjusted to allow the use of inline skates at above-freezing temperatures.

Inline hockey is most popular in areas with indoor artificial inline hockey rinks which make it a year-round sport at the amateur, scholastic, and professional levels. It is a North American professional sport, and is represented by the American Inline Hockey League at the highest level. While there are 116 total members of the International Roller Sports Federation (FIRS) and 64 total members of the International Ice Hockey Federation (IIHF), the United States have finished in most of the coveted 1st, 2nd and 3rd placed at the Inline Hockey World Championships.
