U.S. cities with teams from four major sports

There are 13 U.S. cities with teams from four major sports, where "city" is defined as the entire metropolitan area, and "major professional sports leagues" as:

The New York and the Los Angeles metropolitan areas, the two largest cities in the country, are the only two regions with at least two teams in each major sports league, with the New York metropolitan area being home to three NHL clubs.

Italicized teams play outside the city limits of the metropolitan area's core city or cities; the specific location is given in parentheses. The core city or cities of a metropolitan area are identified in this reference.

Of these metropolitan areas, the only ones with a team in each sport that plays within the limits of its principal city are Chicago, Denver, and Philadelphia. In 2017, Detroit will become the fourth such city when the Pistons begin play out of Little Caesars Arena. In the Twin Cities area, three of the teams play in Minneapolis and one plays in St. Paul, although all four teams are named after the state of Minnesota, not the individual cities. In the San Francisco Bay Area, the core cities of Oakland, San Francisco, and San Jose together have at least one NFL, MLB, NBA, and NHL team, so even though not all teams are within the core cities, all four sports are represented in the core cities. All other areas have at least one sport represented solely by a team (or teams) that plays in a city's suburbs.

The least-populous metropolitan area with at least one team in each of the four major sports is Denver, whose estimated population is 2,552,195. However, Denver is the hub of an urban corridor of approximately 4.5 million people, and is the largest metropolitan area for about 600 miles (970 km).Minnesota is the least populous state to have a team in each major sport.
