We calculate the next-to-leading order (NLO) QCD corrections to the WH{sup 0} production in association with a jet at hadron colliders. We study the impacts of the complete NLO QCD radiative corrections to the integrated cross sections, the scale dependence of the cross sections, and the differential cross sections ((d{sigma}/dcos{theta}), (d{sigma}/dp{sub T})) of the final W-, Higgs boson and jet. We find that the corrections significantly modify the physical observables, and reduce the scale uncertainty of the leading-order cross section. Our results show that by applying the inclusive scheme with p{sub T,j}{sup cut}=20 GeV and taking m{sub H}=120 GeV, {mu}={mu}{sub 0{identical_to}}(1/2)(m{sub W}+m{sub H}), the K-factor is 1.15 for the process pp{yields}W{sup {+-}H0}j+X at the Tevatron, while the K-factors for the processes pp{yields}W{sup -}H{sup 0}j+X and pp{yields}W{sup +}H{sup 0}j+X at the LHC are 1.12 and 1.08, respectively. We conclude that to understand the hadronic associated WH{sup 0} production, it is necessary to study the NLO QCD corrections to the WH{sup 0}j production process which is part of the inclusive WH{sup 0} production.
