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 . We find that the relative corrections of top pair production cross-section can reach about , and the top-antitop spin correlation can reach at the 8(14) TeV LHC in the favorable parameter space.
