During the last couple of years there has been a growing interest in stochastic partial di¡erential equations (SPDEs). Various methods have been used to study SPDEs, see [10] and the references therein. Here we apply white noise analysis to obtain abstract existence and uniqueness theorems. More speci¢cally we combine the ideas of Kondratiev spaces with variational methods for partial di¡erential equations. We show that this approach applies to elliptic, parabolic, as well as hyperbolic SPDEs. To illustrate our ideas on elliptic SPDEs, we prove in Section 4 that there exists a unique solution, u, satisfying
