In the title compound, [Zn(C7H4ClO2)2(C10H8N2)], the ZnII atom is coordinated by two O atoms from two 4-chloro­benzoate ligands and two N atoms from a chelating 2,2′-bipyridine (bpy) mol­ecule in a distorted N2O2 tetra­hedral geometry. The ZnII atom is located on a twofold rotation axis, which also passes through the mid-point of the central C—C bond of the bpy ligand. In the crystal, weak C—H⋯O hydrogen bonds and π–π stacking inter­actions between the pyridine rings of the bpy ligands [centroid–centroid distance = 3.642 (3) Å] link the complex mol­ecules into a two-dimensional supra­molecular structure parallel to (100). An intra­molecular C—H⋯O hydrogen bond is also observed.
