In the title compound, [Cu(C2HCl2O2)(C10H8N2)2](C2HCl2O2)·2H2O, the CuII ion is bonded to two N,N'-bidentate 2,2'-bipyridyl ligands and one O-monodentate 2,2-dichloroacetate anion in a distorted CuON4 trigonal-bipyramidal geometry, with the O atom occupying an equatorial site. In the crystal, the components are linked by O-H...O and O-H...Cl hydrogen bonds.
