  The Mattatuxet River is a river in the U.S. state of Rhode Island. It flows approximately 3 km (2 mi). There are two dams along the river's length.
  
  ## Course
  
  The river rises in North Kingstown from an unnamed pond along Post Road, just east of the RI 138/U.S. 1 interchange. From there, the river flows north to Silver Spring Lake, then south to its mouth at Carr Pond. Below the pond, the river is tidal and becomes the Pettaquamscutt River (Narrow River).
