Abstract: We show that for any $ C^{1+\alpha } $ diffeomorphism of a compact Riemannian manifold, every non-atomic, ergodic, invariant probability measure with non-zero Lyapunov exponents is approximated by uniformly hyperbolic sets in the sense that there exists a sequence $ \Omega _{n} $ of compact, topologically transitive, locally maximal, uniformly hyperbolic sets such that for any sequence $ \{\mu _{n}\} $ of $ f $-invariant ergodic probability measures with $ supp (\mu _{n}) \subseteq \Omega _{n} $ we have $ \mu _{n}\to \mu $ in the weak-$ * $ topology.
