List of North American cities by number of major sports championships

This is a list of cities in the United States and Canada that field or have fielded teams in the four North American professional sports leagues, showing the number of league championships each city has won. The "four major leagues" comprise Major League Baseball, the National Football League, the National Basketball Association and the National Hockey League. The championships won are recorded for the cities only, not the individual franchises. When a team relocates to a new city, the number of championships won in that specific city remain with the city.

Championships are only from the preeminent league in each of the four major sports. NFL championships include all AFL & NFL championship games prior to Super Bowl I. NFL championships include the Super Bowl from 1966–present, AFL championships from 1960-1965 and NFL championship games from 1920-1965. MLB championships begin in 1903 when the first World Series was played. NBA championships began in 1946. The ABA began in 1967 having 8 championships until it merged with the NBA in 1975. NBA championships include all pre-merger ABA championships. Finally, the Stanley Cup is a trophy awarded annually to the playoff champion club of the National Hockey League (NHL). It was donated by the Governor General of Canada Lord Stanley of Preston in 1892, and is the oldest professional sports trophy in North America. Inscribed the Dominion Hockey Challenge Cup, the trophy was first awarded to Canada's amateur ice hockey clubs who won the trophy as the result of challenge games and league play. Professional clubs came to dominate the competition in the early years of the twentieth century, and in 1913 the two major professional ice hockey organizations, the National Hockey Association (NHA) (forerunner of the NHL) and the Pacific Coast Hockey Association (PCHA), reached a gentlemen's agreement in which their respective champions would face each other in an annual series for the Stanley Cup. After a series of league mergers and folds, it became the de facto championship trophy of the NHL in 1926, though it was nominally still subject to external challenge. After 1947, the Cup became the de jure NHL championship prize.
