We develop the concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering. This nonlocality can be realized as a multiparty EPR paradox, and is a key resource for secure quantum secret sharing. Useful properties emerge that are not guaranteed for genuine multipartite entangled states. We derive EPR steering inequalities to demonstrate multipartite EPR steering for GHZ, W and Gaussian continuous variable (CV) states.
