Abstract: In the title centrosymmetric mononuclear Mn^II complex, [Mn(C₇H₆NO₃)₂(H₂O)₄], the Mn^II ion, which lies on an inversion centre, has an octahedral geometry and is six-coordinated by two carbonyl O atoms from two (4-oxo-4H-pyridin-1-yl)acetate (4-OPA^-) anions and four water molecules. The mononuclear units are linked into a two-dimensional network parallel to the (01 $\\overline{1}$ ) plane by O-HO intermolecular hydrogen bonds. Adjacent networks are cross-linked via weak [pi] - [pi] stacking interactions between pyridine rings, with a centroid-centroid distance of 3.758 (3) Å
