A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes that can also take off and land on airfields are in a subclass called amphibian aircraft. Seaplanes and amphibians are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. These aircraft were sometimes called hydroplanes, but currently, this term applies instead to motor-powered watercraft that use hydrofoils to levitate their main hull above the water when running at speed.

"Seaplane!" is the third episode of the fourth season of the animated comedy series Bob's Burgers and the overall 48th episode, and is written by Dan Fybel and Rich Rinaldi and directed by Jennifer Coyle. It aired on Fox in the United States on November 3, 2013.
