Ketchikan (IPA: [ˈkɛ.tʃɪˌkæn]) is the fifth most populous city in the U.S. state of Alaska and the southeasternnmost sizable city in that state.

Ketchikan's economy is based upon tourism and fishing, and the city is known as the "Salmon Capital of the World." The Misty Fjords National Monument is one of the area's major attractions.

Ketchikan is named after Ketchikan Creek, which flows through the town. Ketchikan comes from the Tlingit name for the creek, Kitschk-hin, the meaning of which is unclear, although it may mean "the river belonging to Kitschk." Ketchikan also has the world's largest collection of standing totem poles located at three major locations: Saxman Village, Totem Bight, and the Totem Heritage Center.
