Hyattsville is a city in Prince George's County, Maryland, United States. The population was 17,557 at the 2000 census.
The city was named for its founder, Christopher Clark Hyatt. He purchased his first parcel of land in the area in March 1845. He thought the proximity to the Baltimore & Ohio Railroad tracks and the telegraph lines made the area a good site for a town, and the surrounding farmlands were soon subdivided into housing lots. The name Hyattsville was being used for the settlement by 1859.
As a community inside the Capital Beltway, Hyattsville enjoys easy access to Washington and Baltimore by the West Hyattsville and Prince George's Plaza stops on the Metro subway system's Green Line or by MARC commuter rail trains on the Camden Line in the neighboring town of Riverdale Park.
