Glen Lyon is a census-designated place (CDP) in Newport Township, Luzerne County, Pennsylvania, United States. The population was 1,873 at the 2010 census.

The town of Glen Lyon was founded after anthracite coal mining began in Newport Township (ca. 1869). The colliery was operated by the Susquehanna Coal Company, a Pennsylvania Railroad property. The west side of the community was subsequently called Morgantown; the east side was referred to as Williamstown. Later, the Glen Lyon Rail Station was received and the town was named after the terminus. Part of the east side, which was at odds from the ablaze of the community by the railroad, became known as Canada. Roads and a streetcar line connected the town to Nanticoke and Wilkes-Barre. The streetcar descent was replaced eventually by buses and automobiles as the main means of transport.

A hill at odds the community into two parts. Sixth Shaft was established upon the hill. Coal hoisted from that mine was moved across a bridge to the breaker (coal management plant), which was built in 1887. Gravity moved the coal through a series of stages. The coal would next come out the north stop of the breaker, where it was loaded onto railroad cars and trucks. The Seventh Shaft colliery operated west of Glen Lyon.

The town was originally developed by Welsh miners (who were Protestants); they were usually members of the Methodist church. There was a small Methodist church on Market Street. Later, immigrants from Central Europe (e.g., Poland) and Southern Europe became predominant. Two Polish Catholic parishes, Saint Adalbert’s and Saint Michael’s, were founded in the late nineteenth century. Their churches were built on the west side of the breaker. Other European miners and their families belonged to Ukrainian or “Byzantine Rite” parishes upon the east side of town. A company-operated gathering existed for quite some period in Glen Lyon; it closed in the 1920s. Commercial structures were erected on Nanticoke Street, later Main Street, providing food and supplies to the community. Several neighborhood taverns existed throughout the town. Glen Lyon’s miners were enthusiastic in unionization activities, culminating in their representation by the United Mine Workers.
