We propose a Minimal E-6 Supersymmetric Standard Model (ME6SSM) which allows Planck scale unification, provides a solution to the mu problem and predicts a new Z'. Above the conventional GUT scale M-GUT similar to 10(16) GeV the gauge group corresponds to a left-right symmetric Supersymmetric Pati-Salam model, together with an additional U(1)(psi) gauge group arising from an E-6 gauge group broken near the Planck scale. Below M-GUT the ME6SSM contains three reducible 27 representations of the Standard Model gauge group together with an additional U(1)(X) gauge group, consisting of a novel and non-trivial linear combination of U(1)(psi) and two Pati-Salam generators, which is broken at the TeV scale by the same singlet which also generates the effective mu term, resulting in a new low energy Z' gauge boson. We discuss the phenomenology of the new Z' gauge boson in some detail.
