  We evaluate the supersymmetric QCD corrections to single top quark production
via $q \bar q'\to t \bar b$ at the Fermilab Tevatron in the minimal
supersymmetric model. We find that within the allowed range of squark and
gluino masses the supersymmetric QCD corrections can enhance the cross section
by a few percent. The combined effects of SUSY QCD, SUSY EW, and the Yukawa
couplings can exceed 10% for the smallest allowed $\tan\beta~ (\simeq 0.25)$
but are only a few percent for $\tan\beta >1$.
