In the title compound, [Mn(C12H9O2)2(C7H6N2)2]·H2O, the MnII ion is located on a twofold rotation axis and six-coordinated, displaying a distorted MnN2O4 octa­hedral geometry. The crystal packing is stabilized by N—H⋯O hydrogen bonds, which give rise to a one-dimensional structure along [001], and π–π inter­actions between the imidazole rings and between the benzene rings of the 2-(naphthalen-1-yl)acetate ligands [centroid–centroid distances = 3.761 (3) and 3.728 (4) Å]. The contribution of the electron density associated with the disordered water molecules was not considerd in the final structure model.
