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.
