Nestlé Smarties are a colour-varied sugar-coated chocolate confectionery popular primarily in Canada, the United Kingdom, Ireland, Australia, Spain, Switzerland, Germany,France, Greece, the Nordic countries, South Africa, and the Middle East. They have been manufactured since 1937, originally by H.I. Rowntree & Co..

Smarties are oblate spheroids with a minor axis of about 5 mm (0.2 in) and a major axis of about 15 mm (0.6 in). They come in eight colours: red, orange, yellow, green, blue, violet, pink and brown, although the blue variety was temporarily replaced by a white variety in some countries, while an alternative natural colouring dye of the blue colour was being researched.
