"Tymoviridae" are monopartite single-stranded positive sense RNA plant viruses, belonging to group IV of the Baltimore classification of viruses. The genome consists of one large open reading frame and is capped at the 5’ terminus. The particles are non-enveloped and isometric with a diameter of around 30nm, with an icosahedral structure and a triangulation number of 3.

The largest of three genera is "Tymovirus" with 24 species where as the other genera, "Marafivirus" and "Maculavirus" have 4 and 2 species respectively.

The "Tymoviridae" are a relatively new family, only approved in 2002.

The "Tymoviridae" family include the following genera:
*Genus "Tymovirus"; type species: "Turnip yellow mosaic virus"
*Genus "Marafivirus"; type species: "Maize rayado fino virus"
*Genus "Maculavirus"; type species: "Grapevine fleck virus"
