Un fósforo, cerilla, cerillo o misto es un utensilio fungible, consistente en una varilla de material combustible con un extremo (llamado cabeza) recubierto por una sustancia tal que, al frotar la cabeza contra una superficie rugosa adecuada, el calor producido por el frotamiento hace llegar la cabeza a la temperatura de ignición y esta se enciende. Es uno de los principales inventos de la historia, ya que permitió al ser humano obtener fuego de manera instantánea.

A match is a tool for starting a fire. Typically, modern matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by frictional heat generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder; often coloured for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Some match-like compositions, known as electric matches, are ignited electrically and do not make use of heat from friction.
