Lake Ariel is an unincorporated community in Wayne County, Pennsylvania, United States. It was once the site of an amusement park. The main intersection is dominated by Saint Thomas More Roman Catholic Church, lake elementary school, and the Howe Convenient Market.
Located in northeastern Pennsylvania, Lake Ariel was founded by settlers with the name of Jones, and thus was once known by its people as Jonestown. Although it began as a couple of family farms, Jonestown soon expanded due to the Pennsylvania Coal Company's Gravity Railroad. It brought workers and soon businesses were needed to fulfil their needs, including a post office named Ariel, which would later lead to the change in name of the community.
