The Androscoggin Wayside Park is a protected area and state park in Errol, New Hampshire. The site is located inside the Thirteen Mile Woods Scenic Area and as a part of the Mollidgewock State Park.

Featuring the Androscoggin River, the Androscoggin Wayside Park celebrates the history and preserves the natural setting of the area. Being around for thousands of years already, the river contributed largely in the development of the remote North Country of the state. Named after the river, whose moniker came from the Native American term that refers to spear fishing, the park is now best known for fishing, canoeing, and picnicking.

Like many state parks in the New Hampshire system, the Androscoggin Wayside Park is unstaffed and is open all year round.
