Coaldale is a borough in Schuylkill County, Pennsylvania, United States. Initially settled in 1827, it was incorporated in 1906 from part of the former Rahn Township; it is named for the coal industry—wherein, it was one of the principal early mining centers. Coaldale is in the southern Anthracite Coal region in the Panther Creek Valley, a tributary of the Little Schuylkill River, along which U.S. Route 209 was eventually built between the steep climb up Pisgah Mountain from Nesquehoning (easterly) and its outlet in Tamaqua, approximately five miles to the west.
The town is virtually joined at the hip to nearby Lansford, to its immediate east—as both were founded as company towns on lands owned by and mined by the Lehigh Coal & Navigation Company (LC&N) while technically on opposite sides of the county lines. The history, business situation, and fortunes of not just the two, but of three towns, the third being the nearby Summit Hill, located a few thousand feet upslope, were tied in decades of co-development because the LC&N had built the western terminus of the nation's second railroad, the Summit Hill and Mauch Chunk Gravity Railway to ship coal out, and opened multiple mines throughout Coaldale and Lansford and the rest of the Panther Creek Valley in the days when railroads were coming into their own. The town has a bus stop with a mural on one side reading: "Everybody's Goal Is Mine More Coal" and the other side reading: "A Car More a Day Means More Pay". The area on the western border of the borough is known as Seek.
There is a historical marker for Mother Jones located in Coaldale, as she organized many strikes and protests on behalf of coal miners around the country for improved pay, safer work environment and child labor laws. She organized a march for child workers that started in Coaldale and proceeded to McAdoo. At one trial for Mary Jones, a prosecution lawyer famously said, "there sits the most dangerous woman in America... to put down their tools and walk out".
Herbert Whildin was elected mayor in 2017.
