Interferonen (IFN) zijn natuurlijke eiwitten (glycoproteïnen) die worden afgescheiden door geïnfecteerde cellen van de meeste gewervelde dieren, en dus ook van de mens. Ze spelen een belangrijke rol bij de werking van het immuunsysteem. Interferonen behoren tot de groep cytokinen. De effecten van interferon tegen virussen werden in 1957 ontdekt door Alick Isaacs en Jean Lindenmann.
