Smuttynose Island is one of the Isles of Shoals, located 6 miles off the coast of New Hampshire, but actually in the state of Maine, in the United States. It is part of the town of Kittery, in York County. It was named by fishermen, seeing the island at sea level and noticing how the profuse seaweed at one end looked like the "smutty nose" of some vast sea animal.
The island is best known for two murders that occurred there. On 6 March 1873, two Norwegian women, Karen and Anethe Christensen, were strangled and one struck with a hatchet. A third woman, Maren Hontvet, escaped and hid on the island at a place now called "Maren's Rock".
