Parvovirukset (Parvoviridae) on virusten heimo. Parvovirukset ovat erittäin pienikokoisia, lineaarisia, segmentoitumattomia DNA-viruksia, joissa on keksimäärin kaksi geeniä. Parvovirukset ovat maailman pienimpiä luonnosta löytyviä viruksia (latinalainen nimi parvus tarkoittaa pientä), kooltaan 23–28 nm.
Parvoviruksia tunnetaan ihnimsillä, koirilla ja muilla eläinlajeilla. Ihmisen parvovirus B19 aiheuttaa lukuisia sairauksia, joista yleisin on parvorokko. Suomessa merkittävimmät eläinten parvovirusten aiheuttamat taudit ovat koiran parvovirusripuli, kissarutto ja sioilla parvoviruksen aiheuttamat lisääntymishäiriöt. Näitä tauteja vastaan on käytössä tehokkaat rokotteet.
