  A short review of the theory and phenomenology of Higgs bosons is given, with
focus on the Standard Model (SM) and the minimal supersymmetric extension of
the Standard Model (MSSM). The potential for Higgs boson discovery at the
Tevatron and LHC, and precision Higgs studies at the LHC and a future e+e-
linear collider are briefly surveyed. The phenomenological challenge of the
approach to the decoupling limit, where the properties of the lightest CP-even
Higgs boson of the MSSM are nearly indistinguishable from those of the SM Higgs
boson is emphasized.
