We generalise the electric-magnetic duality in standard Maxwell theory to its non-commutative version. Both spacespace and spacetime non-commutativity are necessary. The duality symmetry is then extended to a general class of non-commutative gauge theories that goes beyond non-commutative electrodynamics. As an application of this symmetry, plane wave solutions are analysed. Dispersion relations following from these solutions show that, in the presence of spacetime non-commutativity, non-commutative electrodynamics admits two waves with distinct polarisations propagating at different velocities in the same direction.
