Dundalk was named after the town of Dundalk (Irish: DĂșn Dealgan) in County Louth, Ireland. Dundalk is considered one of the first inner-ring suburbs of Baltimore. The area now known as Dundalk was explored by John Smith in 1608.
In 1916, the Bethlehem Steel purchased 1,000 acres of farmland near the McShane foundry to develop housing for its shipyard workers. The Dundalk Company was formed to plan a town in the new style, similar to that of the Roland Park area of Baltimore, excluding businesses except at specific spots and leaving land for future development of schools, playing fields, and parks. 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”. The two-story houses had steeply pitched roofs and stucco exteriors.
The Dundalk Historic District was listed on the National Register of Historic Places in 1983.
