Floating islands are a common natural phenomenon that are found in many parts of the world. They exist less commonly as an artificial phenomenon. Floating islands are generally found on marshlands, lakes, and similar wetland locations, and can be many hectares in size.

Sometimes referred to as tussocks, floatons, or suds, natural floating islands are composed of vegetation growing on a buoyant mat of plant roots or other organic detritus.

Floating is a technique commonly used by artists to provide a quick and easy graduated shading (or highlighting) to a project that gives it the look of having depth and dimension. It is one painting technique all serious woodcrafters should master.

The Floating Island is a unique island biome in Subnautica. It is located southwest of the Aurora.
