This is a list of species in the genus Graphis, a lichen-forming fungal genus in the family Graphidaceae. Species of Graphis are crustose lichens that form thin, often pale grey or greenish patches on bark, with elongated, slit-like fruiting bodies that trace dark, sometimes branching lines across the surface—an appearance that inspired the common name "script lichens". Graphis is widespread but especially diverse in tropical and subtropical regions, and it was established in 1763 by the French naturalist Michel Adanson.
