The leading contributions to the electron (or muon) electric dipole moment due to CP violation in the charged Higgs sector are at the two{endash}loop level. A careful model-independent analysis of the heavy fermion contribution is provided. We also consider some specific scenarios to demonstrate how charged Higgs sector CP violation can naturally give rise to large electric dipole moments. Numerical results show that the electron electric dipole moment in such models can lie at the experimentally accessible level. {copyright} {ital 1997} {ital The American Physical Society}
