Pennsylvania Route 191 (PA 191) is a 111.54 mi (179.51 km)-long state highway in the U.S. state of Pennsylvania. The route, a major non-freeway corridor connecting the Lehigh Valley to The Poconos in eastern Pennsylvania, is designated from U.S. Route 22 in Brodhead to the New York state line over the Delaware River at Hancock, New York.

Commissioned on April 17, 1961, the route replaced the PA 12 and PA 90 numbers that were in place from the late 1920s to the 1960s. From 1961 to 1976, PA 191 was routed south of US 22 through Bethlehem and terminated at Pennsylvania Route 309 in Center Valley. Pennsylvania Route 378 replaced the designation from Center Valley to the Lehigh River crossing in Bethlehem.

PA 191 begins at an interchange with U.S. Route 22 in Bethlehem Township, as the Nazareth-Bethlehem Pike, a continuation of Linden Street from downtown Bethlehem. From there, PA 191 runs north-east past some rural and agricultural regions of Northampton County. Along the way, it intersects the eastern terminus of Pennsylvania Route 946 in Lower Nazareth Township.
