Picornaviruses are viruses that belong to the family Picornaviridae. The name is derived from pico meaning small, and RNA referring to the ribonucleic acid genome, so "picornavirus" literally means small RNA virus. Picornaviruses are non-enveloped, positive-stranded RNA viruses with an icosahedral capsid. The genome RNA is unusual because it has a protein on the 5' end that is used as a primer for transcription by RNA polymerase.

Picornaviruses are separated into nine distinct genera and include many important pathogens of humans and animals. The diseases they cause are varied, ranging from acute "common-cold"-like illnesses, to chronic infections in livestock. Two main categories are the enteroviruses and the rhinoviruses although these are soon to be classed together as one single genus-enterovirus. The most important enterovirus is poliovirus. Enteroviruses infect the enteric tract as it is visible from its name. On the other hand, Rhinoviruses infect primarily the nose and the throat. Enteroviruses replicate at 37°C, whereas Rhinoviruses grow better at 33°C, as this is the lower temperature of the nose. Enteroviruses are stable under acid conditions and thus they are able to survive exposure to gastric acid. In contrast, Rhinoviruses are acid-labile and that is the reason why Rhinoviruses are restricted to the nose and throat.

The family Picornaviridae consists of 9 genera: Enterovirus, Rhinovirus, Cardiovirus, Aphthovirus, Hepatovirus, Parechovirus, Erbovirus, Kobuvirus and Teschovirus, plus two soon-to-be-proposed genera provisionally named "Sapelovirus" and "Senecavirus". Additionally, the genera Enterovirus and Rhinovirus are soon to be combined, retaining the former genus name.
