A rubber duck is a toy shaped like a stylized duck, generally yellow with a flat base. It may be made of rubber or rubber-like material such as vinyl plastic. The yellow rubber duck has achieved an iconic status in Western pop culture and is often symbolically linked to bathing. Various novelty variations of the toy are produced.
Its history is linked to the emergence of rubber manufacturing in the late 19th century. The earliest rubber ducks were made from harder rubber.
