Upper Marlboro

Upper Marlboro lies along the Western Branch of the Patuxent River in Prince George's County, Maryland, with residential neighborhoods stretching west from the downtown core. The county courthouse and administration building stand along Main Street, forming the center of public facilities.

English settlers founded the town in 1695 and named it after the first Duke of Marlborough. The river port served for decades as a shipping point for regional tobacco crops.

The name honors John Churchill, reflecting colonial ties to English nobility, while the riverfront location once facilitated tobacco commerce. Today schools and government offices shape daily routines, with residents moving between neighborhoods spread across several postal zones.

County government buildings along Main Street offer services on weekdays, while residential areas spread across a wide territory. Visitors can navigate the compact downtown easily but need a vehicle to reach surrounding neighborhoods.

Five different postal codes cover one-fifth of the entire county area and together form Greater Upper Marlboro. This administrative division reflects the sprawling reach of the region, extending far beyond the town center itself.
