State Route 85 (abbreviated SR 85) is an American road, part of Maine's system of numbered state highways, located in the southern central part of the state.

SR 85 begins at US 302/SR 35 in southern Raymond.

The highway heads north through town and passes along the west side of Crescent Lake.

Locally, it is known as Webbs Mills Road, for its terminus is located in Webbs Mills, a small village in Casco.

The road almost directly parallels SR 121, and provides an alternate route to get to the Lake Region, and thus avoiding the traffic on US 302.
