The Umpachene River is an 8.3-mile-long (13.4 km)[1] tributary of the Housatonic River in New Marlborough, Massachusetts. Issuing from small ponds and wetlands on the east side of town, it meanders generally westward through mostly wooded areas before emptying into the Konkapot River near the village of Southfield.
