Oregon Route 131, known as the Netarts Highway No. 131 (see Oregon highways and routes), is an Oregon state highway that runs between the coastal communities of Oceanside and Tillamook, Oregon, United States. The highway is nine miles (14 km) long.

Oregon Route 131 is a post-2002 number.

The western terminus of Oregon Route 131 is in the town of Oceanside, Oregon, located in between Cape Meares and Cape Lookout in Tillamook County. From there, the highway heads south through Netarts, and then heads east. The highway then turns north, finally turning east before it ends in downtown Tillamook, at an intersection with U.S. Route 101 and Oregon Route 6.

The stretch of the highway between Oceanside, and an intersection south of Netarts, is part of the Three Capes Scenic Route, as is the easternmost stretch of the highway approaching Tillamook.
