  We study the collider phenomenology of a Littlest Higgs model with T-parity.
We first stress the important role of the T-odd SU(2) doublet fermions
(introduced to make the model T-parity invariant) in high energy scattering
processes, such as $q\bar{q}\to W_H^+ W_H^-$ where $W_H^\pm$ are the T-odd
partners of $W$-bosons. Because the mass of the T-odd SU(2) doublet fermions
cannot be too heavy to be consistent with low energy data, they can be
copiously produced at the CERN Large Hadron Collider (LHC). Therefore, we study
the collider phenomenology of the model with emphasis on the contributions of
the T-odd fermion to the production of the heavy T-parity partners (either
bosons or fermions) of the usual particles at the LHC. The production cross
sections and the decay branching ratios of the new heavy particles are
classified and various experimental signatures are discussed.
