Route 14 is a numbered state highway in the U.S. state of Rhode Island. It runs approximately 23 miles (37 km) from Connecticut routes 14 and 14A at the border with Sterling, Connecticut, to Route 6 in Providence.

Route 14 starts at the Connecticut border at an intersection with Connecticut routes 14 and 14A. It runs northeast past the northern terminus of Route 117, and then turns north at an intersection with Rhode Island Route 102. It runs concurrent with Route 102 for a while, and crosses two arms of the Scituate Reservoir on causeways. Route 14 continues east and intersects I-295 at exit 4, then continues towards downtown Providence before ending at the US 6 expressway near the Huntington Expressway.

Route 14 roughly follows the historic Providence and Norwich Turnpike, later renamed to "Plainfield Pike." The only deviation from the original road occurs in Scituate, where approximately 1.5 miles (2.4 km) of original route have been bypassed. Half of this bypassed road is currently submerged under the Scituate Reservoir. Known as "Old Plainfield Pike," the bypassed section can still driven by car from its starting point at Route 102 to Route 12. Beyond Route 12, the original road continues as a paved path. This path extends for approximately .25 miles until reaching the Scituate Reservoir, where it remains underwater for approximately a mile. Emerging on the northeast side of the Reservoir, the path continues for 0.25 miles before rejoining Route 14. The pavement between Route 12 and the Reservoir, and between the Reservoir and Route 14 on the northeast side, is believed to be original from before the Reservoir was created.
