Pennsylvania Route 554 (PA 554) is a highway which runs for 8 miles (14 km) generally north–south in Lycoming County in north central Pennsylvania in the United States.
Starting at its southern end in Washington Township, PA 554 runs generally north to North White Deer Ridge, which it climbs in a series of curves and two hairpin turns.
It crosses into Armstrong Township at the summit and into the valley between North White Deer Ridge and Bald Eagle Mountain, where it passes the Hagermans Run Reservoir.
It then follows Hagermans Run down the north side of Bald Eagle Mountain into the borough of South Williamsport, where it ends at US 15.
By 1941, the northern endpoint was redesignated from US 15 and US 220 in Williamsport to its current alignment.
