We obtain sufficient conditions for the existence of at least three weak solutions of a (p, q)- biharmonic system. We also consider the applications of our main theorem to some special cases of the system. The proof of our main theorem utilizes the variational approaches and a recent theorem of Ricceri on the existence of two global minima of a functional.
