Dunmore is a borough in Lackawanna County, Pennsylvania, United States, adjoining Scranton.

Extensive anthracite coal, brick, stone, and silk interests had led to a rapid increase in the population from 8,315 in 1890 to 23,086 in 1940.

[3] The first European to set foot on Dunmore soil was Count Zinzendorf of Saxony, in 1742, as a missionary to the native people[4] who were Munsee-speaking Delawares.

The territory now encompassing Dunmore was purchased from the natives in 1754 by the Susquehanna Company of Connecticut and became the township of Providence.

Edward Lunnon, Isaac Dolph, James Brown, Philip Swartz and Levi De Puy, purchased land here between 1799–1805.

[4] Stephen Tripp, in 1820, began the area's first business, erecting a saw and grist mill on the Roaring Brook half a mile south of the village.

[5] The village, consisting of but four houses, had a negative existence until the Pennsylvania Coal Company, in 1847–1848, turned it into a growing and diverse town.

Roaring Brook flows from the southeast and turns west through the Nay Aug Gorge in Dunmore to the Lackawanna River in Scranton.

The Lackawanna Railroad operated through the Nay Aug Gorge into Scranton from the Poconos and Northern New Jersey.

[19] In November 2014, the Dunmore borough council approved a $15.63 million agreement for Keystone as a basis for an extension, and a definition of the landfill as a “pre-existing landfill” to ensure Keystone a more favorable interpretation of the borough's zoning ordinance against public opinion.

The current principal of Holy Cross High School is Benjamin Tolerico, their vice-principal is Cathy Chiumento and their dean of students is Kandy Taylor.

I-84/I-380 follows the Nay Aug Gorge westward towards the spaghetti junction interchange with Interstate 81 and U.S. Route 6.
