Akiachak Seaplane Base (ICAO: KKI) is a small public-use seaplane base located in Akiachak, a rural Yup'ik village in the Bethel Census Area of western Alaska. It serves as a critical access point for this remote community, which is situated along the Kuskokwim River and is not connected to the Alaska road system. The facility supports floatplane operations that provide essential air transportation for residents, including mail delivery, medical access, and the movement of supplies. Small regional and bush carriers operate here, as aviation is the primary means of reaching Akiachak from larger hubs such as Bethel. Given its remote location and the nature of seaplane operations, the base offers minimal infrastructure. It plays a vital role in supporting the roughly 700 residents of Akiachak who depend on air transport for connectivity to the broader region.
