We calculate the electroweak corrections of the order O(mt2\over v2) to the QCD production of tt 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 tt 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 t pair is also discussed, including the effect that this has on proposed techniques for measuring the the top quark mass.
