  We calculate the supersymmetric ${\cal O}(\alpha_s)$ QCD corrections to stop
and sbottom decays into vector bosons within the Minimal Supersymmetric
Standard Model. We give analytic formulae and perform a numerical analysis of
these decays. We find that SUSY-QCD corrections to the decay widths are
typically -5% to -10% depending on the squark masses, squark mixing angles, and
the gluino mass.
