Professional ice hockey (hockey) is the competition of ice hockey in which participants are paid to play. Professional competition began in North America in the United States—in Pennsylvania and Michigan—and in Canada around 1900. Professional ice hockey expanded across Canada and the United States and eventually to many other countries. There are major leagues around the world, including the National Hockey League in North America, the Kontinental Hockey League in Europe and Asia, and the Swedish Hockey League in Europe, as well as minor leagues such as the American Hockey League and ECHL in North America, and the Ligue Nord-Américaine de Hockey in Canada. High-level professional hockey is also present in Germany, the Czech Republic, Slovakia, Finland and Switzerland; professional hockey is also played in many other countries, as diverse as Ukraine, the United Kingdom, Austria, Australia and Japan. The major professional women's league is the Professional Women's Hockey League, which began play in 2024.

In professional sports, as opposed to amateur sports, participants receive payment for their performance. Professionalism in sport has come to the fore through a combination of developments. Mass media and increased leisure have brought larger audiences, so that sports organizations or teams can command large incomes. As a result, more sportspeople can afford to make sport their primary career, devoting the training time necessary to increase skills, physical condition, and experience to modern levels of achievement. This proficiency has also helped boost the popularity of sports. In most sports played professionally there are many more amateur than professional players, though amateurs and professionals do not usually compete.
