Pennsylvania Route 997 (PA 997) is a 49.0-mile (78.9 km) route that is located in Franklin and Cumberland counties in central Pennsylvania in the United States. This route runs from the Maryland state line south of Waynesboro, where the road continues into that state as Maryland Route 64 (MD 64), north to PA 233 in the Upper Mifflin Township community of McCrea.

PA 997 heads north from the state line through agricultural areas in the Cumberland Valley and passes through Waynesboro, where it intersects PA 16, and Mont Alto, where it intersects the south end of PA 233, before coming to U.S. Route 30 (US 30) in Greenwood. From here, the route turns northwest and comes to a junction with Interstate 81 (I-81) and PA 696 near Scotland and US 11 in Green Village.

PA 997 crosses PA 433 in Culbertson and heads north along the eastern border of Letterkenny Army Depot to Pleasant Hall, where it crosses PA 533. The route continues north through rural areas and intersects PA 433 near Lurgan and PA 641 in Roxbury before heading northeast and reaching an interchange with the Pennsylvania Turnpike (I-76) near Blue Mountain. PA 997 leaves Franklin County for Cumberland County and intersects the north end of PA 696 before continuing to McCrea.

PA 997 was designated in 1928 between Mont Alto and US 30 in Fayetteville along Mont Alto Road. The same year, the present route between the Maryland border and Waynesboro became part of PA 316 while the section between Lurgan and Roxbury became part of PA 433.

PA 333 was designated in 1928 to run from US 30 in Chambersburg northeast to US 11 in Shippensburg, heading north to Pleasant Hall, west to Upper Strasburg, northeast to Roxbury, east to Newburg, and south to Shippensburg. By 1930, PA 997 was extended south from Mont Alto to PA 16 in Waynesboro, while PA 333 was moved to a more direct alignment between Pleasant Hall and Roxbury (running concurrent with PA 433 between Lurgan and Roxbury) and PA 996 was designated onto the road between Scotland and Green Village.

In 1937, PA 997 was extended south to MD 60 at the Maryland border south of Waynesboro and northwest to US 11 in Green Village, replacing PA 996 between Scotland and Green Village, while the north end of PA 333 was cut back to PA 433 in Lurgan and PA 944 was designated onto the road between Roxbury and McCrea. PA 997 swapped alignments with PA 316 south of Waynesboro in 1941, being rerouted to end at MD 64 at the Maryland border.

PA 333 was rerouted to head southeast from Pleasant Hall to PA 433 in Culbertson in the 1940s, with a section of the former alignment south of Pleasant Hall removed for the Letterkenny Army Depot. PA 997 was extended north from Green Village to PA 233 in McCrea, replacing the entire length of PA 333, PA 433 between Lurgan and Roxbury, and PA 944 between Roxbury and McCrea. The route was shifted east to its current alignment between Mont Alto and north of Fayetteville in 1977.
