The lightest Higgs h could decay invisibly to a pair of LSPs. The heavier Higgs boson can decay predominantly to neutralino, chargino or sfermion pair final states. We will attempt to assess the detection possibilities in these supersymmetric final states. Some particular channels that we may consider are o qqbar -> WH -> Wbbar, Wtau+tau- at Tev33 o invisible Higgs decays at NLC and hadron machines; Higgs decays to supersymmetric states and lighter Higgs bosons o Zh, WW fusion, ttbar Higgs at NLC; pair production of H, A o discovery of a Higgs in the s-channel at a muon collider by scanning
