Virginia State Route 277 (SR 277) is a primary state highway in the U.S. state of Virginia. Known as Fairfax Pike, the state highway runs 4.72 miles (7.60 km) from U.S. Route 11 and SR 631 in Stephens City in southern Frederick County east to US 522 and US 340 at Double Tollgate in the southwestern corner of Clarke County.

SR 277 begins at an intersection with US 11 (Main Street) in the town of Stephens City. SR 631 (Fairfax Street) continues west from the intersection through the Newtown-Stephensburg Historic District and out of town toward the village of Marlboro. SR 277 heads east, leaving the town limits just west of a diamond interchange with Interstate 81. The state highway passes between residential subdivisions and passes to the north of Sherando High School before entering farmland. SR 277 follows the height of land between Wrights Run, which feeds Opequon Creek, to the north and Crooked Run, which is impounded to form Lake Frederick and flows south into the Shenandoah River at Front Royal. SR 277 reaches its eastern terminus immediately to the east of the Frederick–Clarke county line at an intersection with US 522 and US 340. US 522 heads north as Front Royal Pike toward Winchester, US 340 heads east and then north as Lord Fairfax Highway toward Berryville, and US 522 and US 340 join in a concurrency as Winchester Road south toward Front Royal.

Current plans are to move State Route 277 one half mile south of its current location, having it begin one half mile south of its current terminus with US Route 11 and County Route 631 to near the Drake's Family Drive In. The ending terminus will be near Lake Frederick at US Route 522 in Clarke County near the Warren County line.
