Route 114A is an alternate state route to Rhode Island Route 114, located along the Massachusetts – Rhode Island border in East Providence, RI and Seekonk, MA. The road begins and ends within East Providence in Rhode Island at Route 114. Most of the road, however, is located within Seekonk in Massachusetts.

Route 114A begins as Mink Road at an intersection with Route 114 in East Providence. It crosses into the Massachusetts town of Seekonk after 0.1 miles (0.16 km) and continues north as Mink Street then Fall River Avenue through Seekonk center. Route 114A continues north back into Rhode Island, where it ends back at Route 114, which is overlapped with U.S. Route 1A (US 1A) at this point in East Providence.

This is the only instance in Massachusetts of an "A" or "alternate" route carrying the numerics for a highway signed in another state, as Massachusetts Route 114 is over 50 miles (80 km) away, running between Lawrence and Marblehead. Three other such instances of this exist in New England. One is in New Hampshire, where New Hampshire Route 113B is actually a loop off Maine State Route 113. The other two are in Vermont, where Vermont Route 10A is a continuation of New Hampshire Route 10A, a loop off New Hampshire Route 10; and Vermont Route 22A is a continuation of New York Route 22A, a spur off New York Route 22.
