Pennsylvania Route 339 (PA 339) is a 32.8-mile-long (52.8 km) north–south state highway located in Schuylkill, Columbia, and Luzerne counties in Pennsylvania. The southern terminus is at PA 54 in Mahanoy City. The northern terminus is at PA 93 in Nescopeck. The route is a two-lane road that passes through mountainous areas in the eastern part of the state. PA 339 runs north through the Coal Region to Brandonville, where it heads northwest to follow the Catawissa Creek to Mainville. From Mainville, the route passes through farmland to Mifflinville, where it follows the Susquehanna River to Nescopeck. PA 339 forms a concurrency with PA 924 in Brandonville and has an interchange with Interstate 80 (I-80) in Mifflinville.

PA 339 was designated in 1928 to run from U.S. Route 11 (US 11) in Bloomsburg north to PA 115 in Coles Creek. PA 342 was designated onto the stretch of road between the border of Schuylkill and Columbia counties and Mainville. The northern terminus of PA 339 was cut back to PA 115 (now PA 254) south of Benton in the 1930s, with PA 115 replacing the route north of there. PA 342 was extended southeast to PA 45 (now PA 54) in Mahanoy City in the 1930s. In the 1940s, a southern extension of PA 44 replaced PA 342. In the 1960s, PA 339 was shifted to its current alignment. PA 339 replaced the section of PA 44 between Mahanoy City and Mainville while a southern extension of PA 487 replaced the former PA 339 between Bloomsburg and Benton.
