A recursive-circulant $G(n; d)$ is defined to be a circulant graph with $n$ vertices and jumps of powers of $d$. $G(n; d)$ is vertex-transitive, and has some strong hamiltonian properties. $G(n;d)$ has a recursive structure when $n = cd^m$, $1 \leq c < d $ [Theoret. Comput. Sci.244 (2000) 35-62]. In this paper, we will find the automorphism group of some classes of recursive-circulant graphs. In particular, we will find that the automorphism group of $G(2^m; 4)$ is isomorphic with the group $D_{2 \cdot 2^m}$, the dihedral group of order $2^{m+1}$.
