Abstract. Some reverse Hölder type inequalities yielding for monotone or quasimonotone functions of one variable have recently been obtained and applied (see e.g. [2-5], [14]). In this paper we prove a sharp multidimensional integral inequality of this type. It is pointed out that this inequality may be regarded as a unification and extension of many inequalities of this type including some recent results in [1] and [11].
