In this paper, we have defined the weakly symmetric generalized Trans-Sasakian manifold G(WS)n and it has been shown that on such manifold if any two of the vector fields λ,γ,τ, defined by equation (0.3) are orthogonal to ξ, then the third will also be orthogonal to ξ. We have also proved that the scalar curvature r of weakly symmetric generalized Trans-Sasakian manifold G(WS)n, (n>2) satisfies the equation r=2n(α2−β2), where α and β are smooth function and γ≠τ.
