We compute the O({alpha}{sub s}) QCD corrections to the inclusive process e{sup +}e{sup {minus}}{r_arrow}t{bar t}h. Although the total rate is small, it has a distinctive experimental signature and can potentially be used to measure the top-quark{endash}Higgs-boson Yukawa coupling. The QCD corrections increase the rate by a factor of roughly 1.5 for e{sup +}e{sup {minus}}{r_arrow}t{bar t}h at {radical} (s) =500 GeV and M{sub h}=100 GeV. At {radical} (s) =1 TeV, the corrections are small. {copyright} {ital 1999} {ital The American Physical Society}
