We study the effects of O({alpha}{sub s}) supersymmetric QCD (SQCD) corrections on the total production rate and kinematic distributions of polarized and unpolarized top-pair production in pp and pp collisions. At the Fermilab Tevatron pp collider, top-quark pairs are mainly produced via quark-antiquark annihilation, qq{yields}tt, while at the CERN LHC pp collider gluon-gluon scattering, gg{yields}tt, dominates. We compute the complete set of O({alpha}{sub s}) SQCD corrections to both production channels and study their dependence on the parameters of the minimal supersymmetric standard model. In particular, we discuss the prospects for observing strong, loop-induced SUSY effects in top-pair production at the Tevatron run II and the LHC.
