                                        Suppose (X, S) is a S- metric space and P, Q and T are selfmaps of X. If these three maps and the space X satisfy certain conditions, we shall prove that they have a unique common fixed point in this paper. As a consequence we deduce a common fixed point theorem for three selfmaps of a complete S- metric space. Further, we show that a common fixed point theorem for three selfmaps of a metric space proved by S. L. Singh and S. P. Singh ([9]) follows as a particular case of the theorem.
