Beddington Lake is a glacial lake in Washington County, Maine, near Beddington and just east of the Hancock County line. Located close to the junction of Maine State Routes 9 and 193, it is directly connected to the Narraguagus River, which serves as both its main inflow and outflow. Unpaved roads and scattered private homes line the shore, and together they give the lake a rural, lightly developed setting.
