Highway 87 in the U.S. State of Montana is a route running northerly from the Idaho state line at Raynolds Pass to an intersection with U.S. Route 287 about 3 miles (4.8 km) west of Quake Lake, a distance of approximately 9 miles (14 km). The route traverses a high and arid mountain valley, flanked by the Horn Mountains; the land is mostly uninhabited. Raynolds Pass is on the Continental Divide.

The road across Raynolds Pass was first developed into a state highway in 1959, to provide a bypass route after an earthquake temporarily severed the roadway through the upper Madison River canyon to the east. Originally, the Raynolds Pass Road was designated as part of Montana Highway 287; the current number was assigned after US 287 was extended northward through Montana.
