In the title compound, [Zn(C7H4ClO3)2(C12H8N2)(H2O)], the ZnII cation is coordinated by two 4-chloro-2-salicylate anions, one 1,10-phenanthroline ligand and one water mol­ecule in a square-pyramidal coordination geometry; the Zn cation lies 0.4591 (11) Å from the basal plane. The benzene rings of the anions are involved in π–π stacking. The centroid–centroid distance between parallel benzene rings of adjacent mol­ecules is 3.9017 (17) Å, and the centroid–centroid distance between benzene and pyridine rings of adjacent mol­ecules is 3.584 (2) Å. Intra­molecular O—H⋯O hydrogen bonding is present.
