Abstract: In the title mol­ecular salt, C6H6NO2+.C4H3O4-, the 2-carb­oxy­pyridinium cation is essentially planar with a maximum deviation of 0.003 (3) Å. In the crystal, adjacent cations and anions are linked by an extensive system of weak N-H...O, O-H...O and C-H...O inter­actions, forming a layer parallel to the ab plane.
