We examine the one-loop contributions arising in the two-Higgs-doublet model to the {ital W}-boson anomalous magnetic dipole and electric quadrupole form factors for both photon and {ital Z} couplings relevant at collider energies. While the model parameter and {ital q}{sup 2} dependencies of these form factors are found to be significant, the corresponding size of these corrections are relatively small in comparison to unity. They are, however, found to be comparable in magnitude to the usual standard model loop corrections. Radiative corrections to the Higgs-particle masses and couplings due to heavy top quarks are included in the analysis.
