The main objective of the present paper is to introduce a new curvature tensor, called the $\ast$-generalized quasi-conformal curvature tensor, in the setting of Sasakian and $N(k)$-contact metric manifolds. Subsequently, we investigate various semi-symmetric structures associated with this tensor and derive several interesting geometric characterizations and results.
