The city of Baltimore, Maryland, has six public markets, which comprise the oldest continuously operating public market system in the United States. Since 1995, they have been administered by the Baltimore Public Market Corporation, a non-profit organization.
Baltimore's first public market house was established in 1751, some two decades after the of the town. Twelve years later, the first market was constructed. At one point, 11 markets operated across the city. Oversight of the markets was assigned to the Baltimore Comptroller's Office in 1857, then transferred to the Mayor's Office in 1983.
