What is the smallest city that has an MLB team?

Written by Editorial Team | Last Updated: August 2026

When measuring the smallest city that currently hosts a Major League Baseball franchise, the answer depends on whether one looks at municipal city-proper population or total metropolitan area and media market size. In terms of municipal population within official city limits, several Major League Baseball cities have relatively small numbers compared to their regional sprawl, including Miami, Florida, and Minneapolis, Minnesota. However, when evaluating traditional standard metropolitan statistical areas and television media markets, the city of Milwaukee, Wisconsin—home to the Milwaukee Brewers—consistently ranks as the smallest overall market hosting an MLB franchise. Despite Milwaukee having a metropolitan population of under two million residents, the Brewers consistently maintain impressive per-capita attendance figures and intense regional loyalty across Wisconsin. Additionally, during the transitional period where the Athletics play at Sutter Health Park in West Sacramento, California, prior to their planned permanent relocation to Las Vegas, West Sacramento operates with a local city population under sixty thousand residents, serving as the smallest host municipal boundary for big-league games in modern times.
