The left–right twin Higgs (LRTH) model predicts the existence of a pair of charged Higgs bosons φ ± . In this paper, we study the production of the charged Higgs boson pair φ ± at the international linear collider (ILC) and the CERN large hadron collider (LHC). The numerical results show that the production rates are at the level of several tens fb at the ILC, and the process e + e - →φ + φ - can produce adequately distinct multi-jet final states. We also discuss the charged Higgs boson pair production via the process qq̄→φ + φ - at the LHC and estimate in this case the production rates. We find that, as long as the charged Higgs bosons are not too heavy, they can be abundantly produced at the LHC. The possible signatures of these new particles might be detected at the ILC and LHC experiments.
