Alfavirus (Alphavirus) je rod virusov RNK in edini rod v družini togavirusov (Togaviridae).
So srednje veliki ikozaedrični virusi z enoverižno RNK in ovojnico. Povzročajo bolezni pri različnih vrstah vretenčarjev. Večina okužuje tudi členonožce, ki viruse prenašajo, sami pa ne zbolijo.http://www.termania.net/slovarji/mikrobioloski-slovar/6745298/togavirus?query=togavirus&SearchIn=All, Slovenski medicinski slovar - Univerza v Ljubljani, Medicinska fakulteta, vpogled: 25. 9. 2017.
Taksonomija Sprva je družina Togaviridae vključevala tudi današnje Flaviviruse, znotraj rodu Alphavirus. Flavivirusi so bili kasneje razvrščeni v svojo lastno družino, saj so bile s sekvenciranjem ugotovljene zadostne razlike v primerjavi z alfavirusi. Rubella virus was formerly included in the family Togaviridae in its own genus Rubivirus, but is now classified in its own family Matonaviridae. Alphavirus is now the sole genus in the family.
Rod vključuje sledeče vrste:
Aura virus Barmah Forest virus Bebaru virus Caaingua virus Cabassou virus Chikungunya virus Eastern equine encephalitis virus Eilat virus Everglades virus Fort Morgan virus Getah virus Highlands J virus Madariaga virus Mayaro virus Middelburg virus Mosso das Pedras virus Mucambo virus Ndumu virus O'nyong'nyong virus Pixuna virus Rio Negro virus Ross River virus Salmon pancreas disease virus Semliki Forest virus Sindbis virus Southern elephant seal virus Tonate virus Trocara virus Una virus Venezuelan equine encephalitis virus Western equine encephalitis virus Whataroa virus
