In the title salt, C2H8N+·C6H2N3O7−, there is complete transfer of the OH proton from picric acid to the amine. The picrate anions lie almost parallel to the monoclinic (101) plane and are connected by O⋯O short contacts. The ethylaminium and picrate ions are linked through N—H⋯O and C—H⋯O hydrogen bonds along the crystallographic b axis.
