The Turn Point Light Station is an active aid to navigation overlooking Haro Strait from the western tip of Stuart Island, San Juan County, Washington, in the northwest of the United States.

[2][3] The light marks a sharp turn in the shipping lanes at the transition between Haro Strait and Boundary Pass.

Operations at Turn Point commenced in 1893 with the construction of a fog signal building, a two-story keeper's quarters, and a barn.

[6] Electricity for the navigation light and also for the lightkeeper's house was furnished by generators installed in the fog-signal building, in the room previously used to store coal for the old hot-air engines.

[8] Volunteers through the Turn Point Lighthouse Preservation Society[9] offer seasonal docent guided tours of the original 1893 Keepers House.
