The supersymmetric QCD corrections to top quark pair production by q (
$) over bar q annihilation in p ($) over bar p collisions are calculat
ed in the minimal supersymmetric model. We present the analytic expres
sions of the corrections to the total t ($) over bar t production cros
s section at the Fermilab Tevatron. The numerical results show that th
e corrections can enhance the cross section by similar to 10% for favo
rable parameter values.
