Skull Island (Washington)

Skull Island is a 2.5-acre (1.0 ha) uninhabited island at the center of Skull Island State Park in the U.S. state of Washington, in Massacre Bay, off the coast of Orcas Island, the largest of the San Juan Archipelago. It was named for holding skulls and bones of a band of Lummi who were killed by raiding Haida in 1858.

Another Skull Island in the same archipelago is located at 48°27′56″N 122°49′59″W in Mud Bay, part of Lopez Sound, between the Sperry Peninsula of Lopez Island and Fortress Island.
