We present lightlike submanifolds of golden semi-Riemannian manifolds. We prove that there is no radical anti-invariant lightlike submanifold of a golden semi-Riemannian manifold. In particular, we investigate several properties of semi-invariant lightlike submanifolds of golden semi-Riemannian manifolds and get some results. Moreover, we give two examples.
