Pennsylvania Route 857 (PA 857) is an 11.04-mile-long (17.77 km) state highway located within Fayette County, Pennsylvania, United States. The southern terminus of the route is at the West Virginia state line southeast of Gans in Springhill Township, where the route continues south as County Route 857, a secondary state highway. The northern terminus is at an interchange with U.S. Route 119 and Pennsylvania Route 43 in Uniontown.

The roadway runs parallel to PA 43 for all but one mile (1.6 km) of its length.

One mile north of the state line in Springhill Township, PA 857 connects to the current southern terminus of the Mon/Fayette Expressway (PA 43) via Gans Road. The route continues north to the Springhill Township community of Haydentown, where it intersects PA 43 at exit 4 via Rubles Mill Road. PA 857 continues northward to Fairchance, where it interchanges with PA 43 at exit 8 via Big Six Road. PA 857 then continues past Fairchance before terminating at US 119 (Morgantown Road) just east of another interchange with PA 43 in Uniontown.

PA 857 is one of several state route numbers to have been assigned, decommissioned and then reassigned later in a different region. The original PA 857 that was commissioned in 1928 ran for 24 miles along the Ohio River from Pittsburgh's Manchester neighborhood to Rochester in Beaver County. The entire segment was first renumbered in 1935 as a realignment of PA 88. In 1961, the northern terminus of PA 88 was truncated to its current location at PA 51 in the Pittsburgh's Overbrook neighborhood; the remaining segment of former PA 857/PA 88 from the northern end of the West End Bridge to New Castle was renumbered one more time as present-day PA 65.
