Using the experimental value of the K/sub L/-K/sub S/ mass difference, we derive constraints on charged-Higgs-boson couplings in gauge theories of the weak and electromagnetic interactions. These bounds severely restrict the possible magnitude of charged-Higgs-boson effects in K and D meson decays. Our results are based on the observation that charged-Higgs-boson-exchange contributions to K/sup 0/-K-bar/sup 0/ mixing are of order 1/M/sub H/ /sup 2/ whereas the corresponding W-boson contribution is only of order m/sub c/ /sup 2//M/sub W/ /sup 4/.
