Akutan Seaplane Base (IATA: was KQA, FAA LID: KQA) is a public use seaplane base located in Akutan, a city on Akutan Island in the Aleutians East Borough of the U.S. state of Alaska. Scheduled seaplane service was subsidized by the Essential Air Service program until late 2012 when PenAir retired their Grumman Goose amphibious aircraft and a new land-based airport on neighboring Akun Island was built. The new airport is known as Akutan Airport.

As per Federal Aviation Administration records, the airport had 1,346 passenger boardings (enplanements) in calendar year 2008, 1,200 enplanements in 2009, and 1,246 in 2010. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation airport (the commercial service category requires at least 2,500 enplanements per year).
