Dundalk (/ˈdʌndɔːk/ DUN-dawk or /ˈdʌndɒk/ DUN-dok) is an unincorporated community and census-designated place in Baltimore County, Maryland, United States.

[3] The foundry later relocated to the Patterson Park area of Baltimore until a fire during the 1940s caused it to move to 201 East Federal Street.

In 1916, the Bethlehem Steel purchased 1,000 acres (4.0 km2) of farmland near the McShane foundry to develop housing for its shipyard workers.

By 1917, Dundalk proper was founded, at which point it had 62 houses, two stores, a post office, and a telephone exchange.

Streets were laid out in a pedestrian-friendly open grid, with monikers like "Shipway", "Northship", "Flagship", and "Admiral".

Before, during, and after World War II, many Appalachian migrants settled in the Baltimore area, including Dundalk.

[5] Prior to the passage of the Fair Housing Act of 1968, racial covenants were used in Maryland to exclude African-Americans and other minorities.

[1] Most of Dundalk is flat and very near sea level, with a few small hills close to the city of Baltimore to the west.

Interstate 695, the Baltimore Beltway, passes through the district, crossing the Patapsco River on the Francis Scott Key Bridge until its collapse in March 2024.

Until the early 1950s, the line carried the famous "Red Rocket" streetcars, two and three-car trains of wooden trolleys.

The Baltimore County Police Department, Dundalk (Precinct 12), is located at 428 Westham Way and has jurisdiction over the town.
