Locally symmetric K-contact manifolds, or semi-symmetric Sasakian manifolds, are of constant curvature 1 (cf. [10], [4], [9]). The main purpose of this paper is to extend these results and that of [3] considering semisymmetric contact Riemannian manifolds satisfying one condition which generalizes the K-contact condition. Finally we extend some result of [4] and [11] considering contact Riemannian manifolds satisfying ＄R(X, ￥xi)￥cdot S=0＄ where ＄S＄ is the Ricci tensor.
