Abstract: If $ L$ is a lattice, the automorphism group of $ L$ is denoted $ \operatorname{Aut} (L)$. It is known that given a finite abstract group $ H$, there exists a finite distributive lattice $ D$ such that $ \operatorname{Aut} (D) \cong H$. It is also known that one cannot expect to find a finite orthocomplemented distributive (Boolean) lattice $ B$ such that $ \operatorname{Aut} (B) \cong H$. In this paper it is shown that there does exist a finite orthomodular lattice $ L$ such that $ \operatorname{Aut} (L) \cong H$.
