The Silver Swan is an automaton dating from the 18th century and now housed in the Bowes Museum, Barnard Castle, Teesdale, County Durham, England. It was acquired by John Bowes, the museum's founder, from a Parisian jeweller in 1872.

An automaton is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions. Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power or will, like a mechanical robot. The term has long been commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people.
