The Copicut River, or Copecut River, is long stream in the U.S. state of Massachusetts.

The river flows south from Copicut Reservoir (formerly the Copicut Swamp), in Dartmouth and Fall River, to Cornell Pond near Hixville in Dartmouth. From there the Shingle Island River drains into Noquochoke Lake, which the East Branch Westport River drains in turn into the Rhode Island Sound

The river is currently polluted with Polychlorinated biphenyl (PCB) contamination from Re-Solve, Inc., which operated chemical reclamation facility nearby from 1956-1980. In 1983 the Environmental Protection Agency listed the area as a Superfund site, and in 1985 removed of contaminated soils and sludges. Since 1988 the Massachusetts Department of Public Health has advised against consuming fish from Cornell Pond or Copicut River.
