Dalmatia is a census-designated place ^[3] located in Lower Mahanoy Township, Northumberland County in the state of Pennsylvania. The community is located along Pennsylvania Route 147 in southwestern Northumberland County, along the Susquehanna River. As of the 2010 census ^[4] the population was 488 residents.

History

The community was initially called founded in 1798 under the name "Georgetown" before being renamed "Dalmatia" after the historical region of Dalmatia located in contemporary Croatia. ^{[5] [6] [7]} The change seems to have been caused by an attempt of the U.S. Postal Services to establish a post office in the year 1817, which failed due to the fact that the name "Georgetown" was too common. This prompted the locals to change the name, alongside its alleged "resemblance to the Dalmatian coast". ^[7]
