Pennsylvania Route 93 (PA 93) is a 40-mile (64 km) long state route located in northern Pennsylvania. The northern terminus of the route is at Pennsylvania Route 487 in Orangeville. The southern terminus is at U.S. Route 209 east of Nesquehoning. Although the route is signed north–south, PA 93 follows an east–west alignment between Berwick and Orangeville.

PA 93 begins at an intersection with US 209 east of the borough of Nesquehoning. The route proceeds to the northeast from US 209, running amidst the Broad Mountain Range in the largely rural northwest corner of Carbon County. Past the range's summit, PA 93 intersects two quadrant routes, SR 4006 and SR 4010, both leading to the community of Weatherly, prior to entering the first populated area along the route, Beaver Meadows. After a junction with another quadrant route in the center of the borough, PA 93 exits town on Berwick Street and crosses into Luzerne County soon afterward.

A short distance north of the county line, the area surrounding PA 93 transforms from rural mountains to suburbs, increasing in density as the route progresses toward Hazleton. At a junction immediately southeast of Hazleton with Pennsylvania Route 424, a bypass built in 2000 linking PA 93 to Interstate 81, PA 93 becomes East Broad Street, a name it retains as it enters the city.

Though not named Main Street, PA 93 acts as the main thoroughfare through Hazleton, intersecting every state route that enters the city and providing access to I-81 northwest of downtown. At Church Street, PA 93 intersects Pennsylvania Route 309 and becomes West Broad Street. Six blocks west, PA 93 meets Pennsylvania Route 924 at Diamond Avenue. The two routes run concurrent one another for nine blocks to the north along West Hazleton's South Broad Street, splitting at 15th Street. From here, PA 924 heads east and re-enters Hazleton while PA 93 continues northward on North Broad Street, and later Susquehanna Boulevard after North Broad branches off from the route.

At 22nd Street, the area surrounding PA 93 changes once more, this time from dense residential neighborhoods to commercial and industrial centers. PA 93 continues to the northwest through the center, passing the Valmont Industrial Park to the southwest and Laurel Mall to the north prior to interchanging with I-81 at exit 145.

On the opposite side of I-81, the surrounding area takes on a suburban feel once again as PA 93, now the Berwick-Hazleton Highway, passes along the southern edge of Conyngham before entering the Sugarloaf Township community of Sybertsville. Upon exiting Sybertsville, however, PA 93 becomes a largely rural road once again, passing through sparsely populated valleys as it interchanges with Interstate 80 1.5 miles (2.4 km) north of Sybertsville. North of I-80, PA 93 breaks from its northerly alignment and begins to progress due west to avoid the Nescopeck Mountains to its north. After clearing the range, PA 93 follows a northwesterly track through Briggsville, where PA 93 meets the southern terminus of Pennsylvania Route 239, before turning back to the west to pass through Nescopeck, where PA 93 intersects the northern terminus of Pennsylvania Route 339, and enter Columbia County yards from the Susquehanna River.

At the county line, PA 93 turns to the northwest to cross the Susquehanna at a 90 degree angle. While crossing the river, the route briefly enters Briar Creek Township before entering Berwick on the opposite riverbank.

Two blocks into Berwick, PA 93 meets Front Street and 2nd Street, a pair of unidirectional streets carrying U.S. Route 11 through downtown Berwick. PA 93 turns left onto 2nd Street, joining with US 11 along 2nd Street, and later Front Street following the merge of Front and 2nd Streets, to Orange Street, where PA 93 splits from US 11 and heads west out of Berwick.

West of Berwick, the routing of PA 93 is largely dictated by the surrounding terrain, resulting in a series of turns and dips between Fowlersville and Ebenezer Church in North Centre Township. Past Ebenezer Church, however, the routing of PA 93 is fairly linear, traveling due west to Orangeville, where PA 93 terminates at PA 487.
