We compute QCD corrections to the processes e{sup +}e{sup {minus}}{r_arrow}t{bar t}h{sup 0} and pp{r_arrow}t{bar t}h{sup 0} by treating the Higgs boson as a parton which radiates off a heavy quark. This approximation is valid in the limits M{sub h}{lt}{lt}M{sub t} and M{sub h},M{sub t}{lt}{lt}{radical} (s) . The corrections increase the rate for pp{r_arrow}t{bar t}h{sup 0} at the CERN LHC by a factor of 1.2 to 1.5 over the lowest order rate for an intermediate mass Higgs boson, M{sub h}{lt}180 GeV. The QCD corrections are small for e{sup +}e{sup {minus}}{r_arrow}t{bar t}h{sup 0} at {radical} (s) =1 TeV. {copyright} {ital 1998} {ital The American Physical Society}
