The object of the present paper is to characterize ($\kappa,\;\mu$)-contact metric manifolds whose concircular curvature tensor satisfies certain semisymmetry conditions. We also verify that the result holds by a concrete example.

Keywords: ($\kappa,\,\mu$)-contact metric manifolds, $N(\kappa)$-contact metric manifolds, concircular curvature tensor, $\eta$-Einstein manifolds
