The title compound, [Pb2(C7H5O2)2(NO3)2(C12H8N2)2(H2O)2], crystallizes as a dinuclear centrosymmetric dimer containing two PbII atoms bridged by two benzoate ligands. Each PbII atom is seven-coordinated by a water mol­ecule, a nitrate anion, a 1,10-phenanthroline (phen) ligand and two benzoate anions. The crystal packing is stabilized by O—H⋯O hydrogen bonds and by π–π stacking between neighboring phen ligands, with a centroid–centroid distance of 3.557 (3) Å.
