An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurized gas. For smaller boats, the floor and hull beneath it is often flexible. On boats longer than 3 metres/10 feet, the floor often consists of three to five rigid plywood or aluminum sheets fixed between the tubes but not joined rigidly together. Often the transom is rigid, providing a location and structure for mounting an outboard motor.Some inflatable boats have been designed to be disassembled and packed into in a small volume, so they can easily be stored and transported to water when needed. Here the boat when inflated is kept rigid crossways by a foldable removable thwart. This feature allows such boats to be used as life rafts for larger boats or aircraft, and for travel or recreational purposes.

Other terms for inflatable boats are "inflatable dinghy", "rubber dinghy", "inflatable" or "rubber duck".
