The Blue Mountain Tunnel is one of two tunnels through Blue Mountain in Pennsylvania, located west of Newburg. It is one of seven tunnels completed for the Pennsylvania Turnpike mainline, and at 4,339 feet (1,323 m) in length, is the shortest of the four still in use today. The Blue Mountain Tunnel is 600 ft (180 m) to the east of the Kittatinny Mountain Tunnel, separated by the Gunter Valley.
- Lehigh Tunnel, on the Northeast Extension of the PA turnpike, also cuts through Blue Mountain; but was given a different name to prevent confusion with the Blue Mountain tunnel farther west.
