  In this work, we investigate the one-loop QCD correction to top pair
production in the littlest Higgs model with T-parity at the LHC. We calculate
the relative correction of the top pair production cross section and
top-antitop spin correlation at the LHC for $\sqrt{s}=8,14$ TeV. We find that
the relative corrections of top pair production cross section can reach about
$-0.35\%$, and the top-antitop spin correlation can reach $1.7\%$($2\%$) at the
8(14) TeV LHC in the favorable parameter space.
