Let $\Gamma$ be a $k-$regular graph with the second maximum eigenvalue $\lambda$. Then $\Gamma$ is said o be Ramanujan graph if $\lambda\leq 2\sqrt{k-1}.$ Let $G$ be a finite group and $\Gamma=Cay(G,S)$ be a Cayley graph related to $G$. The aim of this paper is to investigate the Ramanujan Cayley graphs of sporadic groups.
