The American Hockey League (AHL) is a professional ice hockey league based in the United States and Canada that serves as the primary developmental league for the National Hockey League (NHL). As of the 2023–24 AHL season, 31 of the 32 AHL teams had an official affiliation with an NHL team; immediately following season's end, the Chicago Wolves and Carolina Hurricanes finalized an affiliation agreement, resulting in all AHL teams having an NHL affiliation for the upcoming 2024–25 season. Historically, when an NHL team does not have an AHL affiliate, its players are assigned to AHL teams affiliated with other NHL franchises.

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.
