Dundalk is an unincorporated community and a census-designated place in Baltimore County, Maryland, United States. The population was 62,306 at the 2000 census. In 1960 and 1970, Dundalk was the largest unincorporated community in Maryland. It was named after the town of Dundalk, Ireland. Dundalk is considered one of the first inner-ring suburbs of Baltimore.
The area now known as Dundalk was first explored by John Smith in 1608, when while conducting an expedition up the Chesapeake Bay he landed on the area known as the Patapsco Neck. Up until this time, the area was occupied by the tribes of the Susquehanna Indians.
In 1664 Thomas Todd of Virginia purchased 1,150 acres (4.7 km2) of land on the Patapsco Neck, this being the first deed in Baltimore County. The original house, “Todd’s Inheritance”, was burnt by the British during the War of 1812, Battle of North Point. After the war the house was rebuilt, and it still stands today as a historical landmark.
