Abstract
We study electric-magnetic duality rotations for noncommutative electromagnetism (NCEM). We express NCEM as a nonlinear commutative U(1) gauge theory and show that it is self-dual when the noncommutativity parameter \theta is light-like (e.g. \theta^{0i}=\theta^{1i}). This implies, in the slowly varying field approximation, self-duality of NCEM to all orders in \theta.
