Abstract: We prove the following Artin type approximation theorem for smooth CR mappings: given $ M\subset \mathbb{C}^N$ a connected real-analytic CR submanifold that is minimal at some point, $ M^\prime\subset \mathbb{C}^{N^\prime}$ a real-analytic subset, and $ H\colon M\to M^\prime$ a $ \mathcal{C}^{\infty}$-smooth CR mapping, there exists a dense open subset $ \mathcal{O}\subset M$ such that for any $ q\in \mathcal{O}$ and any positive integer $ k$ there exists a germ at $ q$ of a real-analytic CR mapping $ H^k\colon (M,q)\to M^\prime$ whose $ k$-jet at $ q$ agrees with that of $ H$ up to order $ k$.
