We present a precise calculation of the lightest neutral Higgs boson production associated with top-quark pair at a linear collider. The full one-loop electroweak O({alpha}{sub ew}) contributions to the process e{sup +}e{sup -}{yields}tth{sup 0} within the minimal supersymmetric standard model (MSSM) are included. We analyze the dependence of the electroweak corrections on the MSSM parameters such as M{sub A{sup 0}}, tan{beta}, M{sub 2} A{sub f}, M{sub SUSY} and {mu}. The results show that the full one-loop electroweak radiative corrections turn out to be about -20% quantitatively and thus are important for future e{sup +}e{sup -} linear colliders.
