In the crystal of the title compound, C7H7NO3, molecules associate into infinite chains via O—H⋯O(NO2) hydrogen bonds propagating in the  direction. These chains are linked via C—H⋯O(NO2) hydrogen bonds to form double-stranded ribbons lying parallel to the ac plane. The ribbons stack along the b axis by means of π–π interactions involving the benzene rings and the nitro group. The centroid–centroid distances of the alternating parallel aromatic rings are 3.6514 (7) and 3.8044 (7) Å.
