  We calculate the electroweak corrections of the order $O({m_t^2\over v^2})$
to the QCD production of $t\bar{t}$ pairs via $q+qbar->t+tbar$ at hadron
colliders and show that these corrections to the total production rate are
small. This correction can be characterized as increasing the cross section
most near the threshold region, where top quark signals are important, while
the corrections become negative at higher $t\bar{t}$ energies where the top
quark is a background for heavy Higgs boson searches or investigations
involving the strongly interacting longitudinal $W$ system. The polarization of
the $t\bar t$ pair is also discussed, including the effect that this has on
proposed techniques for measuring the the top quark mass.
