In the context of the little Higgs models, we discuss single production of the new charged gauge bosons in association with top quark at the CERN Large Hadron Collider (LHC). We find that the new charged gauge bosons WH- and X-, which are predicted by the littlest Higgs model and the SU(3) simple model, respectively, can be abundantly produced at the LHC. However, since the main backgrounds coming from the processes and are very large, the values of the ratios NW and NX are very small in most of the parameter space. It is only possible to detect the signal of the gauge boson WH- via the process at the LHC in a small region of the parameter space.
