The Barrington River is a tidal extension of Runnins River in the U.S. states of Rhode Island and Massachusetts. It flows approximately 6 km (4 mi). There are no dams along the river's length.
It has also historically been important for shellfishing and boating. Since May 1998, the river has been permanently closed to fishing due to fecal coliform pollution.
The river begins at Hundred Acre Cove which is fed to the north by Runnins River which is where the river flows into Seekonk, Massachusetts. The river then flows southeast to Barrington where it converges with the Warren River.
Below is a list of all crossings over the Barrington River. The list starts at the headwaters and goes downstream.
