Swoyersville is a borough in Luzerne County, Pennsylvania, United States. The population was 5,157 at the 2000 census. Swoyersville is located within the Wyoming Valley West School District.
The borough of Swoyersville, Pennsylvania was named for mine owner John Henry Swoyer. Originally called Swoyerville, the town held a special vote in the 1950s to decide whether to add an "s" to the town's name. The measure passed and the town name became Swoyersville.
Swoyersville's economy was formerly based on coal mining, until most of the town's mines ceased production in the 1950s. Work continued at the colliery on Main Street in Swoyersville well into the 1960s. In 1972, the town was severely flooded by Susquehanna River in the aftermath of Hurricane Agnes. There was great concern at that time, that many of the flooded abandoned mine tunnels, running underneath Swoyersville, would cave-in. Fortunately, the cave-ins never occurred.
