In this work it is shown that given a connected $C^{\infty}$-manifold $M$ of dimension $\geq 2$ and a finite subgroup $G\subset \operatorname{Diff}(M)$, there exists a complete vector field $X$ on $M$ such that its automorphism group equals $G\times \mathbb{R}$, where the factor $\mathbb{R}$ comes from the flow of $X$.

Keywords: Finite group, group action, vector field
