A plant virus that causes mottled light and dark green mosaic patterns on the leaves of tobacco, tomato and other solanaceous crops, and that was the first virus ever discovered, isolated by Martinus Beijerinck in 1898 after Dmitri Ivanovsky's earlier filtration experiments. It remains a significant pathogen of tobacco and greenhouse tomato production and, because of its extreme stability, a widely used model system in plant virology.

Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves. TMV was the first virus to be discovered.
