In this paper we give general conditions that guarantee the analyticity of ${\mathcal C}^\infty$-smooth CR-mappings between real-analytic CR-submanifolds $M\subset\C^N$ and $M'\subset\C^{N'}$. The proof of the analyticity is based on results on holomorphic and meromorphic extension of functions on wedge-like domains to boundary points that may be of independent interest.
