We propose a simple nonconforming virtual element for plate bending problems, which has few local degrees of freedom and provides the optimal convergence in \(H^2\)-norm. Moreover, we prove the optimal error estimates in \(H^1\)- and \(L^2\)-norm. The nonconforming virtual element is constructed for any order of accuracy, but not \(C^0\)-continuous. It is worth mentioning that, for the lowest-order case on triangular meshes the simplified nonconforming virtual element coincides with the well-known Morley element, so it can be taken as the extension of the Morley element to polygonal meshes. Finally, we verify the optimal convergence in \(H^2\)-norm for the nonconforming virtual element by some numerical tests.
