List of seaplanes and amphibious aircraft
The following is a list of seaplanes and amphibious aircraft, which includes floatplanes and flying boats, by country of origin.
Seaplanes are any aircraft that has the capability of landing on water while amphibious aircraft are equipped with wheels to alight on land, as well as being able to land on the water. Flying boats rely on the fuselage or hull for buoyancy, while floatplanes rely on external pontoons or floats. Some experimental aircraft used specially designed skis to skim across the water but did not always have a corresponding ability to float.
This list does not include ekranoplans, 'Wing-In-Ground-effect', water-skimmers, wingships or similar vehicles reliant on ground effect.
