contents The multiplication theorem for univariate Hermite polynomials $H_k(λx)$ is well-known. In this paper we generalize this result to multivariate Hermite polynomials ${\rm H}_{\bf k}({\mathbfΛ}{\bf x};{\mathbfΣ})$, and use this result to derive a multiplication theorem for univariate polynomials applied to inner-products $H_k({\mathbfλ}^{\rm T} {\bf x})$.
