In the present paper, we study curvature properties of η-Ricci solitons on para-Kenmotsu manifolds. We obtain some results of η-Ricci solitons on para-Kenmotsu manifolds satisfying R(ξ, X).C = 0, R(ξ, X). M̃ = 0, R(ξ, X).P = 0, R(ξ, X). C̃ = 0 and R(ξ, X).H = 0, where C, M̃, P, C̃ and H are a quasi-conformal curvature tensor, a M-projective curvature tensor, a pseudo-projective curvature tensor, and a concircular curvature tensor and conharmonic curvature tensor, respectively.

Keywords: η-Ricci solitons, almost paracontact structure, pseudo-projective curvature tensor, M-projective curvature tensor, conharmonic curvature tensor, quasi-conformal curvature tensor, concircular curvature tensor.
