Akhiok is an Alutiiq village dependent upon fishing and subsistence activities. The original village of Kashukugniut was occupied by Russians in the early 19th century. The community was originally a sea otter hunting settlement, located at Humpy Cove. The name Akhiok was reported in the 1880 census. In 1881, residents relocated to the present site at Alitak Bay. The relocation was, in part, based on the switch to a fishing economy. Most families gain their livelihood from fishing, either directly by fishing for salmon and halibut or by working in a nearby cannery. The community's Russian Orthodox church, Protection of the Theotokos Chapel, was built around 1900 at the site of an earlier structure. A post office was established in 1933. Residents of nearby Kaguyak relocated to Akhiok after the 1964 earthquake and tsunami destroyed their village. The city was incorporated in 1972.
