Kitoi Bay Seaplane Base (IATA/ICAO: KKB) is a small, remote seaplane facility located at Kitoi Bay on Afognak Island, Alaska, United States. It serves as a point of access to the wilderness areas of Afognak Island, including the Afognak Island State Park, and is primarily used by floatplanes serving private, charter, and recreational traffic. The base operates in a region accessible almost exclusively by air or water, given the lack of road connections to the broader Alaska highway system. Floatplane services provide a vital link for residents, hunters, fishermen, and ecotourism visitors to this remote corner of the Kodiak Archipelago.
