Moosic ( MOO-zik) is a borough in Lackawanna County, Pennsylvania, 6 miles (10 km) south of downtown Scranton and 13 miles (21 km) northeast of downtown Wilkes-Barre, on the Lackawanna River.
Moosic is in a former coal-mining region. A few older industries existed at one time, including the manufacturing of canvas gloves and silk products. The population was 5,719 at the 2010 census.
The name "Moosic" probably derives from the Unami language of the Lenape people, meaning "elk place". The Lenape, a Native American people, are the earliest-known inhabitants of Moosic. The borough was incorporated on December 9, 1898. Before incorporation, the villages of Moosic and Greenwood had been a part of Lackawanna Township. From 1886 to 1987, Moosic was the site of Rocky Glen Park, an amusement park. The former grounds are now a Pennsylvania state historical marker.
