The playing surface in ice hockey is called a rink, more specifically an ice hockey rink.
An ice hockey rink is a sheet of ice enclosed by boards and protective glass. Its markings organize play into zones and help officials judge offsides, faceoffs, goals, and other situations. The red center line, blue lines, goal lines, faceoff circles, and goal creases are all part of the rink’s familiar layout.
The word “rink” has Scottish origins. It originally referred to the course or playing area used for curling, but the term remained in use as ice hockey developed and dedicated hockey facilities became common. It is not limited to hockey: skating, curling, figure skating, and other winter sports also use rinks.
At the highest levels, rink dimensions vary by governing body. NHL rinks are narrower than the larger international surfaces used in many IIHF competitions and Olympic tournaments. The difference affects available space, passing lanes, and the amount of room players have to build speed.
“Pitch” usually refers to field sports such as soccer, “court” to sports such as basketball, and “field” to outdoor games. Hockey’s standard term is rink.
