We derive the holographic entanglement entropy contribution from pure and mixed gravitational Chern-Simons(CS) terms in AdS$$_{2k+1}$$. This is done through two different methods : first, by a direct evaluation of CS action in a holographic replica geometry and second by a descent of Dong's derivation applied to the corresponding anomaly polynomial. In lower dimensions $(k=1,2)$, the formula coincides with the Wald-Tachikawa formula for black hole entropy from gravitational CS terms. New extrinsic curvature corrections appear for $$k\geq 3$$ : we give explicit and concise expressions for the two pure gravitational CS terms in AdS$$_7$$ and present various consistency checks, including agreements with the black hole entropy formula when evaluated at the bifurcation surface.
