The complete next-to-leading order (NLO) QCD corrections to charged Higgs boson associated production with top quark through b g → tH^- at the CERN Large Hadron Collider are calculated in the minimal supersymmetric standard model (MSSM) and two-Higgs-doublet model in the M̅S̅ scheme. The NLO QCD corrections can reduce the scale dependence of the leading order (LO) cross section. The K-factor (defined as the ratio of the NLO cross section to the LO one) does not depend on tanβ if the same quark
