Three sea turtle species (leatherback, loggerhead, and green) occur infrequently within Olympic Coast National Marine Sanctuary. Of these, the leatherback sea turtle is the most likely to occur.

All three species are listed under the Endangered Species Act. Sea turtles use the sanctuary for foraging but breed in tropical habitats.
