  We analyze the supersymmetric (SUSY) QCD contribution to the $h^0 b \bar{b}$
coupling at one loop in the Minimal Supersymmetric Model (MSSM) in the
decoupling limit. Analytic expressions in the large SUSY mass region are
derived and the decoupling behavior of the corrections is examined in various
limiting cases, where some or all of the SUSY mass parameters become large. We
show that in the decoupling limit of large SUSY mass parameters and large
CP-odd Higgs mass, the $h^0 b \bar b$ coupling approaches its Standard Model
value at one loop. However, the onset of decoupling is delayed when $\tan\beta$
is large. In addition, the one-loop SUSY-QCD corrections decouple if the masses
of either the bottom squarks or the gluino are separately taken large; although
the approach to decoupling is significantly slower in the latter case.
