Dutch Harbor is a harbor on Amaknak Island in Unalaska, Alaska. It was the location of the Battle of Dutch Harbor in June 1942, and was one of the few sites in the United States to be subjected to aerial bombardment by a foreign power during World War II. It was also one of the few sites, besides the attack on Pearl Harbor in Hawaii, in incorporated U.S. territory to be bombed by the Japanese in the war.
Dutch Harbor is now the home of an important fishing industry.
