Some effects of the charged and neutral Higgs scalars in two-doublet theories on the decays of heavy quarkonia are discussed. Large changes in the rate for S13(tt)bb via charged-Higgs-boson exchange are possible as are decays of S01(QQ) states into pairs of scalar/pseudoscalar Higgs particles. We also discuss the decay S13(QQ)H+H- for a hypothetical fourth-generation quarkonium and find that it can dominate the decay rate.
