The Cape Flattery Light is a historic lighthouse structure located at the entrance to the Strait of Juan de Fuca near Neah Bay, Clallam County, in the U.S. state of Washington,[3] within the Makah Indian Reservation.

The deactivated lighthouse sits on Tatoosh Island, which is named after Chief Tatooche of the Makah Tribe.

The lighthouse's light was decommissioned after a 30-foot (9.1 m) skeletal structure with a solar-powered beacon fitted with six-year solar pack batteries was built on the island in 2008.

[9] In 2009, the Coast Guard began cleanup operations in anticipation of handing the historic lighthouse to the Makah tribe, who own Tatoosh Island.
