Supersymmetric Higgs Bosons: a Theoretical Introduction

After an introduction to the Higgs sector of supersymmetric extensions of the Standard Model, recent results on radiative corrections to Higgs boson masses and couplings are reviewed. The phenomenology of supersymmetric Higgs searches at large hadron colliders and at a possible linear $\epem$ collider is also described. (Invited talk at the Workshop `Ten years of SUSY confronting experiment', CERN, 7--9 September 1992, to appear in the Proceedings)
