The West Branch Delaware River, approximately 90 mi (144 km) long in the U.S. states of New York and Pennsylvania, is one of the two branches, along with the East Branch, that join to form the Delaware River. Along most of its course, it flows through a mountainous area of New York in the western Catskill Mountains.

It rises in Schoharie County, New York and flows generally southwest, entering Delaware County and flowing past Stamford and Delhi. In southwestern Delaware County it flows in an increasingly winding course through the mountains, generally southwest. At Stilesville it is impounded to form the Cannonsville Reservoir. At Deposit, on the border between Broome and Delaware counties, it turns sharply to the southeast and is paralleled by New York State Route 17. It joins the East Branch at Hancock to form the Delaware. For the lower 6 mi (10 km) it forms part of the boundary between New York and Pennsylvania.
