Lansford is a county-border borough in Carbon County, Pennsylvania, United States, located 37 miles northwest of Allentown and 19 miles south of Hazleton in the Panther Creek Valley about 72 miles from Greater Philadelphia and abutting the cross-county sister-city of Coaldale in Schuylkill County. The whole valley was owned and subdivided into separate lots by the historically important Lehigh Coal & Navigation Company which likely settled some structures on the lands by 1827.Lansford grew with the development of local anthracite coal mines, and was named after Asa Lansford Foster, who was an advocate for merging the small "patch towns" that developed in the area surrounding the anthracite coal mines. The population was 3,941 at the 2010 Census, a steep decline from a high of 9,632 at the 1930 census common to many mining towns in northeastern Pennsylvania.
