In this paper, we discuss the Kaluza-Klein threshold correction to low-energy gauge couplings in theories with warped extra dimension, which might be crucial for the gauge coupling unification when the warping is sizable. Explicit expressions of one-loop thresholds are derived for generic five-dimensional (5D) gauge theory on a slice of 5D anti-de Sitter space (AdS(5)), where some of the bulk gauge symmetries are broken by orbifold boundary conditions and/or by bulk Higgs vacuum values. The effects of the mass mixing between the bulk fields with different orbifold parities are included, as such a mixing is required in some classes of realistic warped unification models.
